CHAPTER 2

SAFETY

This safety alert symbol means Attention! Become alert! Your safety is involved! It stresses an attitude of safety consciousness and can be foun d

throughout this Operator’s Manual and on the decals on the machine. Before operating this machine, read and study the follo wing safety information.

Be sure that everyone who operates or works with this machine, whether family member or employee, is familiar with these safety precautions. It is essential to have competent and careful operators, who are not physically or mentally impaired, and who are thoroughly trained in the safe operation of the machine and the handling of loads. It is recommended that the operator be capable of obtaining a valid motor vehicle operator’s license.

The use of skid-steer loaders is subject to certain hazards that cannot be eliminated by mechanical means, but only by exercising intelligence, care and common sense. Such hazards include, hillside operation, overloading, instability of the load, poor maintenance and using the equipment for a purpose for which it is not intended or designed.

Gehl ALWAYS considers the operator’s safety when designing its machinery, and guards exposed moving parts for the operator ’s protection. However, some areas cannot be guarded or shielded in order to assure proper operation. This Operator’s Manual and decals on the machine warn of additional hazards, and they should be read and observed closely.

Some photographs in this manual may show doors, guards or shields open or removed for illustrative purposes only. Be sure that all doors, guards and shields are in their proper operating positions before st arting the engine to operate the unit.

Different applications may require optional safety equipment, such as a back-up alarm, mirror, strobe light or an impact-resistant front door. Be sure you know the job site hazards and equip the machine as needed.

“DANGER” indicates an imminently hazardous situation, which, if not avoided, will

result in death or serious injury.

“WARNING” indicates a potentially hazardous situation, which, if not avoided, could result

in death or serious injury.

“CAUTION” indicates a potentially hazardous situation, which, if not avoided may result in

minor or moderate injury. May also alert against unsafe practices.

Mandatory Safety Shutdown Procedure

Before cleaning, adjusting, lubricating or servicing the unit, or leaving it unattended:

1. Move the drive cont rol handle(s) to the neutral position.

2. Lowe r the lift arm and attachment completely. If the lift arm must be left in the raised position, BE SURE to properly engage the lift arm su pport device (page 22).

3. Move th e throttle to the l ow idle positi on, shut off the engine and remove t he key.

4. Before exiting, m ove the lift/tilt control(s) to verify that the controls do not cause movement of the lift arm and hitch.

Safety Reminders

Before Starting

¾ Do not modify the ROPS/FOPS unless instructed to do so in installation

instructions. Modifications such as welding, drilling or cutting can weaken the structure and reduce the protection it provides. A damaged ROPS/FOPS cannot be repaired – it must be replaced.

¾ To ensure safe operation, replace damaged or worn-out parts with genuine

Gehl service parts.

¾ Gehl loaders are designed and intended to be used only with Gehl attach-

ments and approved attachments. To avoid possible personal injury, equipment damage and performance problems, use only attachments that are approved for use on and within the operating capacity of the machine. Contact your dealer or Gehl Company for information on attachment approval and compatibility with specific machine models. Gehl cannot be responsible if the machine is used with a non-approved attachment.

¾ Remove all trash and debris from the machine each day, especially in the

engine compartment, to minimize the risk of fire.

¾ Always face the loader and use the handholds and steps when getting on and

off the loader. Do not jump off the loader.

¾ Never use starting fluid (ether). ¾ Walk around the machine an d warn all nearby personnel before starting the

machine.

¾ Always perform a daily inspection of the machine before using it. Look for

damage, loose or missing parts, leaks, etc.

Page 11

917387/BP0310 7

During Operation

¾ Machine stability is affected by: load being carried, height of the load,

machine speed, abrupt control movements and driving over uneven terrain.

DISREGARDING ANY OF THESE FACTORS CAN CAUSE THE LOADER TO TIP, THROWING THE OPERATOR OUT OF THE SEAT OR LOADER, RESULTING IN DEATH OR SERIOUS INJURY.

Therefore: ALWAYS operate with the seatbelt fastened and the restraint bar lowered. Do not exceed the machine’s Rated Operating Capacity. Carry the load low. Move the controls smoothly and gradually, and operate at speeds appropriate for the conditions.

¾ When operating on inclines or ramps, always travel with the heavier end of

the loader toward the top of the incline for additional stability.

¾ Do not raise or drop a loaded bucket or fork suddenly. Abrupt movements

under load can cause serious instability.

¾ Never activate the float function with the bucket or attachment loaded or

raised, because this will cause the lift arm to lower rapidly.

¾ Do not drive too close to an excavation or ditch; be sure that the surrounding

ground has adequate strength to support the weight of the loader and the load.

¾ Never carry riders. Do not allow others to ride on the machine or attachments,

because they could fall or cause an accident.

¾ Always look to the rear before backing up the skid-steer loader. ¾ Operate the controls only from the operator’s seat. ¾ Always keep hands and feet inside the operator ’s compartment while oper-

ating the machine.

¾ New operators must operate the loader in an open area away from bystanders.

Practice with the controls until the loader can be operated safely and efficiently.

¾ Wear safety gog gles and head protection wh ile operating the machine. Oper-

ator must wear protective clothing when appropriate.

¾ Exhaust fumes can kill. Do not operate this machine in an enclosed area

unless there is adequate ventilation.

¾ When parking the machine and before leaving the seat, check the restraint bar

for proper operation. The restraint bar, when raised, deactivates the lift/tilt control and auxiliary hydraulics, and applies the parking brake.

Maintenance

¾ Never attempt to by-pass the key switch to start the engine. Use only the

jump-starting procedure detailed in the Operation chapter of this manual.

¾ Never use your hands to search for hydraulic fluid leaks. Inst ead, use a piece

of paper or cardboard. Escaping fluid under pressure can b e invisible and can penetrate the skin and cause serious injury. If any fluid is injected into your skin, see a doctor at once. Injected fluid must be surgically removed by a doctor or gangrene may result.

Page 12

8 917387/BP0310

¾ Always wear safety glasses with side shields when striking metal against

metal. In addition, it is recommended that a softer (chip-resistant) m aterial be used to cushion the blow. Failure to heed could lead to serious injury to the eyes or other parts of the body.

¾ Do not smoke or have any spark-producing equipment in the area while

filling the fuel tank or while working on the fuel or hydraulic sy stems.

Potential Hazards

A skid-steer loader operator must ALWAYS be conscious of the work ing environment. Operator actions, the environmental conditions and the job being preformed require the full attention of the operator so that safety precautions can be taken.

ALWAYS maintain a safe distance from electric power lines and avoid contact with any electrically charged conductor or gas line. Accidental contact or rupture can result in electrocution or an explosion. Contact the North American One-Call Referral System at 8-1-1 in the U.S., or 1-888-258-0808 in the U.S and Canada, for the local “Digger's Hotline” number or the proper local authorities for utility line locations BEFORE starting to dig!

Exposure to crystalline silica (found in sand, soil and rocks) has b een associated with silicosis, a debilitating and often fatal lung disease. A Hazard Review (Pub. No. 2002-129) by the U.S. National Institute fo r Occupational Safety and Health (NIOSH) indicates a significant risk of chronic silicosis for workers exposed to inhaled crystalline silica over a working lifetime. NIOSH recommends an exposure limit of 0.05 mg/m

as a time-weighted average for up to a 10-hr. workday during a 40-hr. workweek. NIOSH also recommends substituting less hazardous materials when feasible, using respiratory protect ion and regular medical examinations for exposed workers.

Safety Decals

The skid-steer loader has decals that provide safety information and precautions around the loader. These decals must be kept legible. If missing or illegible, they must be replaced promptly. Replacements can be obtained from your Gehl dealer. If there is a decal on a part that is to be replaced, be sure that the decal is applied to the replacement part.

New Decal Application

Surfaces must be free of dirt, dust, grease and foreign material before applying the decal. Remove the smaller portion of the decal backing paper and apply the exposed adhesive to the clean surface, maintaining proper position and alignment. Peel the rest of the backing paper and ap ply hand pressure to smooth out the decal surface. Refer to the following pages for proper decal location. Text decals begin on page 9; no-text decals begin on page 13.

CHAPTER 3

CONTROLS AND SAFETY EQUIPMENT

Become familiar with and know how to use all

safety devices and controls on the skid-steer loader before operating it. Know how to stop loader operation before starting it. This Gehl loader is designed and intended to be used only with Gehl attachments or Gehl-approved referral attachments or accessories. Gehl cannot be responsible for operator safety if the loader is used with non-approved attachments.

Guards and Shields

Whenever possible and without affecting loader operation, guards and shields are provided to protect against potentially hazardous areas. In many places, safety decals are also provided to warn of potential hazards and/or to display special operating procedures.

Read and thoroughly understand all safety

decals on the loader before operating it. Do not operate the loader unless all factory-installed guards and shields are properly secured in place.

Operator Restraint Bar

Lower the operator restraint bar after entering the operator’s compartment and sitting in the seat. The restraint bar is securely anchored to the ROPS/FOPS. The operator must be seated with the restraint bar in its lowered position t o start or operate the skid-steer loader. Refer to Safety Interlock System on page 20 for more information.

The restraint bar provides for-aft adjustment that allows the operator to determine the most comfortable position of the restraint bar. The right and left portions of the restraint bar system can be adjusted independent of one another by pushing the lever on the lower inside of either pad. The restraint pad can then be used to adjust to the desired position. The restraint pad locks in place when it is released.

Never defeat the operator restraint bar or seat

switch electrically or mechanically. Always wear the seatbelt.

WARNING

Page 24

20 917387/BP0310

Operator’s Seat

The seat is mounted on rails for rearward and forward repositioning. A springloaded lever activates the seat position adjustment mechanism.

Suspension seat: A weight adjustment knob is provided for individual operator adjustment.

Air Suspension Seat: Adjust air suspension seat by pushing in the knob on the air seat to increase the amount of suspension. Pull knob out to release air and decrease the suspension level.

Upper-Torso Restraint

Always wear the upper-torso restraint when operating in high speed.

The seatbelt should always be fastened during operation.

Important: Inspect the seatbelt(s) for damage before use, and replace if damaged. Keep seatbelt(s) clean. Use only soap and water to wash seatbelt(s). Cleaning solvents can cause damage to seatbelt(s).

Safety Interlock System

Hydraloc™

NEVER defeat the safety interlock system by mechanically or electrically bypassing any

switches, relays or solenoid valves.

An interlock system is provided on the loader for operator safety. Together with solenoid valves, switches and relays, the interlock system:

¾ Prevents the engine from starting unless the operator is sitting on the seat and

the operator restraint bar is lowered.

¾ Disables the lift arm, auxiliary hydraulics, attachment tilt and wheel drives

whenever the operator leaves the seat, turns the keyswitch to OFF or raises the restraint bar.

Testing the Safety Interlock System

Before exiting the machine, check the safety interlock system for proper operation:

Restraint Bar

With the engine running, raise the restraint bar. Test each of the controls. There should be no more than a slight movement of the lift arm, hitch and machine. If there is any significant movement, troubleshoot and correct the problem immediately. Contact your dealer if necessary.

Seat Switch

With the engine off and the restraint bar lowered, unfasten the seatbelt, and lift your weight off the seat. Try to start the engine. If the engine starts, turn off the engine, troubleshoot and correct the problem. Contact your dealer if necessary.

ROPS/FOPS

The ROPS/FOPS (Roll-Over/Falling Object Protective Structure) is designed to provide protection for the operator from falling objects and in a tip over accident, if the operator is secured inside the operator’s compartment by the seatbelt and restraint bar.

Never operate the loader with the ROPS/FOPS removed or locked back.

Parking Brake

This skid-steer loader is equipped with a spring-applied, hydraulic-released parking brake. The parking brake engages when the operator lifts the restraint bar, exits the seat or shuts off the engine. The brake can also be applied manually by using the switch located on the left instrument panel. A red indicator in the switch lights when the parking brake is applied.

Rear Window Emergency Exit

The ROPS/FOPS rear window has three functions: noise reduction, flying objects barrier and emergency exit.

To use the emergency exit, pull on the yellow warning tag at the top of the window and remove the seal. Push or kick out the window and then exit.

See your local automotive glass specialist to reinstall the window.

Lift Arm Support Device

The lift arm support device is used as a cylinder lock to prevent the raised lift arm from lowering unexpectedly. Be sure to install the support device when the lift arm is raised for service. When the support device is not being used, return it to its storage position. The support device is a safety device, which must be kept in proper operating condition at all times. The following steps ensure correct usage:

With the key switch OFF and the solenoid valve

working properly, the lift arm will stay raised when the lift control is moved to lower the lift arm. If the valve does not hold the lift am and it begins to lower do not leave the operator ’s compartment. Instead, lower the lift arm and exit the machine. Then, contact your Gehl dealer immediately to determine why the lift arm lowers while the key switch is OFF.

Installation

To install the lift arm support device:

1. Raise the lift arm to full height.

2. Stop the engine.

3. Move the lift arm control to “lower”

to verify that the lift arm is being held in the raised position by the safety interlock system.

4. Have an assistant remove the lift arm

support device from its storage location (Figure 4) on the right side of the machine and install the lift arm support device on the left lift cylinder (Figure 3).

A) Or if an assistant is not available, double-check that the lift arm is being held in the raised position, and then carefully exit the machine, and install the lift arm support device on the left lift cylinder (Figure 3).

5. Restart engine.

6. Slowly l ower the lift arm until it engages and locks against the lift arm support device.

7. Stop the engine, and exit that machine.

Removal

The safest method of installing and removing the lift

arm support device requires two people – one person inside the loader and another person outside the loader to install the support device.

To return the lift arm support device to its storage position:

1. Start the engine;

2. Raise the lift arm fully;

3. Stop the engine;

4. Verify that the lift arm is being held in the raised position by the safety in ter-

lock system.

With the key

switch OFF and the solenoid valve for the safety interlock system functioning properly, the lift arm will stay raised when the lift control is moved to “lower”. If the lift arm moves, do NOT leave the operator’s compartment. Instead, have an assistant remove the support device for you. Then, contact your Gehl dealer to determine the reason why the lift arm lowers while the key switch is in the OFF position.

5. Ha ve an assistant rem ove the lift arm support device.

A) Or, if an assistant is not available verify that the l ift arm is being held in the raised position, and then exit the machine, remove the lift arm support device and carefully re-enter the machine.

6. Lower th e lift arm and secure the lift arm support device with the hand kno b

in the storage location (Figure 4).

Joystick Controls

The loader may be equipped with dual joystick controls, (Figure 13). The left joystick controls the drive, and the right joystick controls the lift/tilt.

Drive Controls

Forward, reverse, speed and turning maneuvers are accomplished by movement of the left joystick. To go forward, push the drive control forward; for reverse, pull the control rearward. To turn right, push the control right; to turn left, push the control left. To go forward and left, move the control forward and left. To go forward and right, move the control forward and right. To move back and left, move the control back and to the right. To move back and right, move the control back and to the left.

Be sure the joystick controls are in neutral

before starting the engine. Operate the controls gradually and smoothly. Excessive speed and quick control movements without regard for conditions and circumstances are hazardous and could cause an accident.

Moving the joystick farther from neutral increases the speed steadily to the maximum travel speed. Tractive effort decreases as speed increases. For maximum tractive effort, move the joystick only slightly away from the neutral position. The engine may stall if the control is moved too far forward when loading the bucket.

Lift/Tilt Control

Moving the lift arm and tilting the attachment are accomplished by movement of the right joystick. To raise the lift arm, pull the control straight rearward; to

lower the lift arm, push the control straight forward. To tilt the attach ment fo r- ward and downward, move the control to the right; to tilt the attachment up and back, move the control to the left.

Note: The speed of the lift/tilt motion is directly prop ortional to the amount of joystick movement and engine speed.

To place the lift arm into the “float” position, push and hold the left button on the right joystick. This mode allows the lowered lift arm to follow the grou nd contour while traveling over changing ground conditions. A n indicator lamp in the left instrument panel will blink when float is activated.

Never push the float control button with the attachment raised, because this will cause

the lift arm to lower very rapidly.

Releasing the float button will cancel the float mode if the b utton was pressed less than five seconds. If the float mode button is pressed longer than five seconds, the float feature will stay on and the float indicator lam p will stay lighted until the button is pressed again or the machine is turned off.

Hand/Foot Controls

The loader may be equipped with hand/foot controls (Figure 14). The handles control the drive and the foot pedals control the lift/tilt.

Drive Controls

Forward, reverse, speed and turning maneuvers are accomplished by movement of the control handles. To go forward, push both handles forward; for reverse, pull both handles rearward. For turning, move one handle farther forward or rearward than the other handle. Turn direction is determined by which handle is moved farther forward. To turn left, mov e the right handle farther forward than the left handle; to turn right, move the left handle farther forward than the right handle. For sharp tu rns, move the handles in opposite directions.

Be sure the controls are in neutral before starting the

engine. Operate the controls gradually and smoothly. Excessive speed and quick control movements without regard fo r condition s and circumstances are hazardous and could cause an accident.

Moving the handles farther from neutral increases the speed steadily to the maximum travel speed. Tractive effort decreases as speed increases. For maximum tractive effort, move the handles only slightly away from the neut ral positions. The engine will stall if the handles are moved too far forward when loading the bucket.

Auxiliary Hydraulic System

Auxiliary hydraulics are used with attachments that have a mechanism requiring hydraulic power.

Always be sure the auxiliary hydraulic control is in neu-

tral before starting the loader or disconnecting the auxiliary hydraulic couplers.

Standard-Flow Auxiliary Hydraulic Control

Loaders are equipped with a standard-flow auxiliary hydraulic system with flatface couplers. The couplers are located under the lift arm on the left side.

Hand/Foot and Joystick Control Loaders Equipped with Electric Auxiliary: The yellow thumb switch located on the righthand control controls the direction and amount of flow. The farther the switch is moved from center, the higher the flow to the auxiliary circuit. The direction of flow is reversed when the thumb switch is moved in the opposite direction from the center. For continuous operation, move the switch in either direction and pull the red trigger button, located on the front of the grip for 5 seconds, and release. To cancel continuous operation, pull the red button or move the yellow switch in either direction.

High-Flow Auxiliary Hydraulic Control (optional)

In addition to a standard-flow auxiliary hydraulic system, some loaders are equipped with a reversible high-flow auxiliary hydraulic system. These couplers are located on the right lift arm. The highflow auxiliary hydraulic system is used for operating certain hydraulic attachments (e.g., cold planer, snowblower) that require higher flows.

The high-flow auxiliary switch controls the direction of hydraulic oil flow. The switch is located on the upper left side instrument panel. Push the right side of the rocker switch for forward flow, or the left side for reverse flow. To disengage, push and release either side of the switch. Turning off the machine, raising the restraint bar, or restarting the engine will also reset the high-flow to neutral. A lamp on either side of the switch will illuminate when the high-flow auxiliary hydraulic system is engaged.

CHAPTER 4

OPERATION

Before starting the engine and operating the

loader, review and comply with all safety recommendations in the Safety chapter of this manual. Know how to stop the loader before starting it. Also, be sure to fasten and properly adjust the seatbelt(s) and lower the operator restraint bar.

Before Starting the Engine

Before starting the engine and running the loader, refer to the Controls and Safety Equipment chapter and become familiar with the various operating controls, indi-

cators and safety devices on the loader.

Fuel

The engine requires low sulfur (“LSD”) or ultra-low sulfur diesel (“ULSD”) fuel to maintain proper engine performance. Yanmar will allow up to a 5% (B5) mixture of BioDiesel.

Important: The use of fuel other than LSD or ULSD will damage the engine.

Starting the Engine

The following procedure is recommended for starting the engine:

1. Carefully step up onto the back of the bucket or attachment and grasp the

handholds to enter the operator’s compartment.

2. Fasten the seatbelt(s) and lower the restraint bar.

3. Verify the following:

¾ the lift/tilt, drive and auxiliary hydraulic controls are in their neutral

positions,

¾ the parking brake switch is ON.

Note: When the key is turned to the RUN position, an indicator lamp will light on the instrument panel and a buzzer will sound momentarily to remind users to fasten the seatbelt.

4. Turn the key to the START position.

Note: If temperature is below 32°F (0°C), see Cold-Starting Procedure, on page 38.

Important: Do not engage the starter for longer than 15 seconds at a time. Longer use can overheat and damage the starter. If the engine fails to start within 15 seconds, return the key to the OFF position. Allow the starter to cool for 20 seconds and repeat step 4.

WARNING

Page 42

38 917387/BP0310

After the engine starts, allow a five minute low idle warm-up period before operating the controls.

Important: If the indicator warning lamps do not go off, stop the engine and investigate the cause.

Cold-Starting

If the temperature is below 32°F (0°C), the following is recommended to make starting the engine easier:

¾ Replace the engine oil with SAE 10W-30 oil, or lighter as recommended

by the viscosity chart;

¾ Make sure the battery is fully charged; ¾ Install a block heater on the engine.

Let the engine run for a minimum of five minutes to warm the engine and hydraulic fluid before operating the loader.

A block heater is recommended for starting in temperatures of 20°F (-7°C) or lower. See your dealer for heater options.

Cold-Starting Procedure

Do not use starting fluid (ether) with pre-heat systems. An explosion can result, which can

cause engine damage, injury or death.

1. Turn the key to the RUN position. If the pre-heat lamp on the right instrument panel comes on, wait until it goes out.

2. Turn the key to the START position.

3. If engine does no t start, return key to OFF position, wait seconds and repeat steps 1 and 2.

Stopping the Loader

The following procedure is the recommended sequence for stopping the loader:

1. Check that the drive control handle(s) is (are) in neutral position.

2. Lowe r the li ft arm and rest the attachment on the ground.

3. Turn throttle knob back to the low idle position (and rel ease the throttle pedal for joystick control machines).

4. Turn the keyswitch to the OFF position and remove the key.

5. Move the li ft/tilt control to verify that the safety int erlock system is preventing movement.

6. Raise the restraint bar, unfasten the seatbelt(s) and grasp the handholds while climbing out of the operator’s compartment.

WARNING

Page 43

917387/BP0310 39

Note: The skid-steer loader is equipped with a spring-applied automatic parkin g brake. The parking brake is applied when the operator lifts the restraint bar, leaves the operator’s seat or shuts off the engine, or actuates the parking brake switch.

Parking the Loader

Park the loader away from traffic on level ground. If this is not possible, park the loader across the incline and block the tires to prevent movement.

Jump-starting

If the battery becomes discharged or does not have enough power to start the engine, use jumper cables and the following procedure to jump-start the engine.

The ONLY safe method for jump-starting a

discharged battery is for TWO PEOPLE to perform the following procedure. The second person removes the jumper cables so that the operator does not have to leave the operator’s compartment with the engine running. NEVER make jumper cable connections directly to the starter solenoid of either engine. DO NOT start the engine from any position other than on the operator’s seat and then ONLY after being sure ALL controls are in “neutral.”

Closely follow the procedure, in order, to avoid personal injury. In addition, to protect your eyes wear safety glasses and avoid leaning over the batteries while jump-starting.

DO NOT jump-start the battery if it is frozen, because it may rupture or explode.

Note: BE SURE the jumper battery is a 12-volt D.C. battery.

1. Turn the keyswitches of both vehicles to OFF be sure both vehicles are in

“neutral” and NOT touching each other.

2. Connect the positive (+) jumper cable to the positive (+) batt ery terminal on

the disabled loader first. DO NOT allow the positive clamps to touch any metal other than the positive (+) battery terminals. Th e battery may be easily accessed by removing the access panel located on the left-rear tower.

3. Connect the other end of the positive jumper cable to the jumper vehicle’s

battery positive (+) terminal.

4. Connect the negative (-) jumper cable to the jumper vehicle’ s battery negative

(-) terminal.

5. Make the final negative (-) jumper cable connection to the disabled loader’s

engine block or loader frame (ground) – NOT to the disabl ed batt ery’s negative post. If connected to the engine, keep the jumper clamp away from the battery, fuel lines and moving parts, and the negative jump stud (if equipped.) .

6. Start the loader. If it does not start at once, start the jumper vehicle’s engine to

avoid excessive drain on the booster battery.

WARNING

Page 44

40 917387/BP0310

7. After the disabled loader is started and running smoothly, have the second person remove the jumper cables [negative (-) jumper cable first] from the jumper vehicle’s battery and then from the disabled loader, while being careful NOT to short the two cables together.

Allow sufficient time for the skid-steer loader battery to build up a charge before operating the loader or shut off the engine.

Changing Attachments

To prevent unexpected release of the attach-

ment from the hitch, be sure to properly secure the hitch latch pins by rotating the latch levers fully (manual All-Tach

hitch), or by verifying that the pin flags moved

fully to the outside of the hitch. (Power-A-Tach

hitch.)

On a manual hitch (Figure 17), two latch levers engage the latch pins to secure the attachment.

Connecting Attachments

1. Manual hitch: Rotate the latch lever

to the right as view from the front to fully retract the latch pins.

Power hitch: Activate the switches to unlock the hitch and fully retract the latch pins. (See page 25 for a detailed description of this procedure.)

2. Start the loader engine and be sure the

lift arm is lowered and in contact with the loader frame.

3. Align the loader squarely with the

back of the attachment.

4. Tilt the hitch forward until the top edge of the hitch is below the flange on the

back side of the attachment and centered between the vertical plates.

5. Slowly drive the loader forward and, at the same time, tilt the hitch back to

engage the flange on the back side of the attachment.

6. Stop forward t ravel when the flange is engag ed, but continue to tilt th e hitch

back to lift the attachment off the ground.

7. M anual hitch: Exercise the MANDATORY SA FETY SHUTDOWN PRO-

CEDURE (page 6). Leave the operator’s compartment and rotate the latch lever to the left when viewed from the front to fully engage the latch pins.

Power hitch: Press and hold th e switch on the left instrument panel to energize the system. press the bottom of the rocker switch on the right instrument panel to extend the hitch pins and to lock the hitch and fully eng age the lat ch pi ns.

Connecting Auxiliary Hydraulic Couplings

Note: With the engine off, key in the ON position and th e restraint bar down, the auxiliary hydraulic control can be moved to relieve any pressure in the hydraulic system. Because the auxiliary hydraulics system is controlled using pilot pressure stored in an accumulator, the engine must have been run recently.

Standard-Flow Auxiliary Hydraulics

Couplers are located on the left lift arm. When the auxiliary control switch is activated, the top coupler is “pressure,” and the bottom coupler is “return.” The smaller center coupler is for the case drain.

High-Flow Auxiliary Hydraulics

Couplers are located on the right lift arm. When the auxiliary control is activated, the top coupler is “pressure,” and the bottom coupler is “return.” The smaller center coupler is for the case drain.

Only connect high-flow attachment couplers to the high-flow auxiliary couplers.

Removing Attachments

1. Tilt the hitch back until the attachment is off the ground.

2. Exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 6).

3. With the engine off, leave the operator’s compartment and disconnect the auxiliary hydraulic hoses.

4. M anual hitch: Rotate the latch lever to the right when viewed from the front to fully retract the latch pins.

Power hitch: Start the engine, press and hold the switch on the left instrument panel to energize the system and press the top of the rocker switch on the right instrument panel to retract the hitch pins to unlock the hitch and fully retract the latch pins.

5. Start the engine (if it is not already on) and be sure that t he lift arm is fully lowered and in contact with the loader frame.

6. Tilt the hitch forward and slowly back the loader away until the attachment is free from the loader.

Self-Leveling (optional)

The feature is intended to automatically keep the attachment level while the lift arm is being raised.

Using a Bucket

Always maintain a safe distance from electric

power lines and avoid contact with any electrically charged conductor or gas line. Accidental contact or rupture can result in electrocution or an explosion. Co ntact the “Call Before You Dig” referral system at 8-1-1 in the U.S., or 888-2580808 in the U.S. and Canada or proper local authorities for utility line locations before starting to dig.

Driving over Rough Terrain

When traveling over rough terrain, drive slowly with the bucket lowered.

Driving on an Incline

When traveling on an incline, travel with the heavy end pointing uphill.

Digging with a Bucket

Approach the digging site with the lift arm slightly raised and the bucket tilted forward until the edge contacts the ground. Dig into the ground by driving forward and gradually lowering the lift arm (Figure 18).

When the bucket is filled, tilt the bucket back, and back the loader away from the material. Rest the lift arm against the loader frame before proceeding to the dumping area.

Always carry the loaded bucket with the lift

arm resting on the loader frame. For additional stability when operating on inclines, always travel with the heavier end of the loader toward the top of the incline.

Loading a Bucket

Approach the pile with the lift arm fully lowered and the bucket tilted slightly forward until the edge contacts the ground. Drive forward into the pile, lifting the lift arm and tilting back the bucket to fill it. Back away from the pile (Figure 19).

WARNING

917387/BP0310 43

Dumping the Load onto a Pile

Carry a loaded bucket as low as possible until the pile is reached. Gradually stop forward motion and raise the lift arm high enough so that the bucket clears the top of the pile. Then, slowly move the loader ahead to position the bucket to dump the material on top of the pile. Dump the material and then back the loader away while tilting the bucket back and lowering the lift arm.

Never push the “float” button with the bucket or attachment raised, because this will cause

the lift arm to lower rapidly.

Dumping the Load into a Truck (or Hopper)

Carry the loaded bucket low and approach the vehicle (or hopper.) Stop as close to the side of the truck (or hopper) as possible while allowing for clearance to raise the lift arm and loaded bucket. Next, raise the lift arm until the bucket clears the top of the truck (or hopper) and move the loader ahead to position the bucket over the inside of the truck (or hopper.) Dump the material and then back away while tilting the bucket back and lowering the lift arm (Figure 20).

Dumping the Load over an Embankment

Do not drive too close to an excavation or

ditch. Be sure the surrounding ground has adequate strength to support the weight of the loader and the load.

Carry the loaded bucket as low as possible while traveling to the dumping area. Stop the loader where the bucket extends half-way over the edge of the embankment. Tilt the bucket forward and raise the lift arm to dump the material. Dump the material, and then back away from the embankment while tilting t he bucket back and lowering the lift arm.

Scraping with a Bucket

For scraping, the loader should be operated in the forward direction. Position the lift arm down against the loader frame. Tilt the bucket cutting edge forward at a slight angle to the surface being scraped. While traveling slowly forward with the bucket in this position, material can flow over the cutting edge and collect inside the bucket (Figure 21).

Leveling the Ground

Drive the loader to the far edge of the area to be leveled. Tilt the bucket forward to position the bucket cutting edge at a 30 to 45 degree angle to the surface being leveled. Then place the lift arm into “float” position and drive the loader rearward, dragging the dirt and, at the same time, leveling it (Figure 22).

Note: The “float” detent is activated by pressing the left button on the right control handle.

Check that the work area is clear of people and obstacles. Always look in the direction of

travel.

Vibration Information

Compact construction equipment is generally used in harsh environments. This type of usage can expose an operator to uncomfortable levels of vibration. It is useful to understand exposure to vibration levels when operating compact eq uipment and what can be done to reduce vibration exposure. As a result, equipment operation can be more efficient, productive and safe.

An operator’s exposure to vibration occurs in two ways:

¾ Whole-Body Vibration (WBV) ¾ Hand-Arm Vibration (HAV)

This section will cover primarily WBV issues, because evaluations have shown that operation of mobile compact construction equipment on jobsites typically results in HAV levels less than the allowed exposure limit of 2.5 m/s

Employers in Member States of the European Union must comply with the Physical Agents (vibration) Directive, 2002/44/EC.

Effective control of vibration exposure for an operator involves more than just vibration levels on the machine. The job site, how the machine is used, and proper training all play important roles in reducing vibration exposure.

Vibration exposure results from:

¾ worksite conditions ¾ how the machine is operated ¾ the machine characteristics

Common causes of high WBV vibration levels:

¾ Using a machine that is improper for the task ¾ Work site with potholes, ruts and debris

The vibration directive places the responsibility for compliance on employers. Actions that should be followed by employers include:

¾ Assess the levels of vibration exposure. ¾ Determine from this assessment if operators will be exposed to vibration

levels above the limits stated in the directive.

¾ Take appropriate actions to reduce operator’s exposure to vibrat ion. ¾ Provide operators with information and training to reduce their exposure to

vibration.

¾ Keep good records and update operations and training on a regular basis.

If the assessment concludes that vibration level exposure is too high, one or more of the following actions may be necessary:

1. Train operators

¾ Perform operations (accelerating, steering, braking, etc.) in a smooth

manner .

¾ Adjust machine speed appropriately. ¾ Adjust the controls, mirrors and seat suspension for comfortable operation. ¾ Travel across the smoothest parts of the work site and avoid ruts and pot-

holes.

2. Choose proper equipment for the job

¾ Use machines with the proper power and capacity. ¾ Select machines with good suspension seats. ¾ Look for controls that are easy to use. ¾ Ensure good visibility from the op erator’s position.

3. Maintain the work site

¾ Smooth ruts and fill potholes in traffic areas whenever possible. ¾ Clean up debris frequently. ¾ Vary traffic patterns to avoid exposure to rough terrain.

4. Maintain the equipment

¾ Ensure correct tire pressures. ¾ Check that seat suspension and all controls work smoothly and properly.

Vibration Levels

The following table shows typical Whole-Body Vibration levels for Gehl skid-steer loaders.

Typical Whole-Body Vibration Levels*

*Vibration levels were recorded using a range of skid-steer loader models driven by

an experienced operator on flat conditioned soil and handling gravel in the activities indicated. For additional vibration data, refer to ISO TR 25398.

The data above indicates that Gehl skid-steer loaders, when used in a similar manner as described above, do not exceed the limit value for Whole-Body Vibrations, and can therefore be operated by one operator for at least 8 hours per day.

Note: When the skid-steer loader is operated in accordance with the instructions in the operator ’s manual, the hand-arm vibration levels are below the exposure action value of 2.5 m/s

Checking the Water Separator

The separator is located between the fuel tank and main fuel filter and is used to remove finely dispersed water in diesel fuel. Check on a daily basis and drain if necessary. Water can be drained from the separator by o pening the valve located at the bottom of the separator bowl.

Engine Diagnostic Chart

When detecting failures, the engine electronic control unit (ECU) flashes the failure lamp to alert the operator to the occurrence of the failure conditions. The failure lamp will light for two seconds when th e engine electron ic control unit is powered on. This allows checking if the engine electronic control unit is supplied with power normally. (The failure lamp is an essential way for checking or diagnosing the engine electronic control unit.)

Flashing patterns of the failure lamp are showing in Figure 35. When accelerator sensor failure (flashing 5 short (0.5 seconds) times) and Exhaust Gas Recirculation valve failure (flashing 1-3 long (1.5 seconds) and 3 short times) occurs, the failure lamp flashes as shown in Figure 35. When two or more failures have occurred simultaneously, the failure lamp indicates all the failures in order of increasing number of flashes cyclically.

Bucket Cutting Edge

The bucket cutting edge should be replaced when it is worn to within 1 in. (25 mm) of the bucket body.

Alternator/Fan Belt

Refer to the separate engine manual for setting proper belt tension. If the belt is worn, cracked or otherwise deteriorated, replace the belt following the procedure in the engine manual.

Wheel Nuts

Wheel nut torque must be checked before initial operation and every two hours thereafter until the wheel mounting hardware torque remains at 180 ft.-lbs. (244 N·m). When wheels are removed and reinstalled this procedure must be repeated.

Lift Arm Pivots

The All-Tach® pivot should be torqued every 250 hours to 240 ft. lbs. (325 N·m). Refer to the Maintenance Interval Chart (page 81).

Page 73

917387/BP0310 69

Cooling System

Important: Check the cooling system daily to prevent overheating, loss of performance and engine damage.

Cleaning the Cooling System

Allow sufficient time for the oil radiator to cool before working on or near it. Parts get

extremely hot during operation and can burn you.

The radiator assembly is mounted between the engine and the hinged rear door. When operating correctly, air is blown through the openings between the fins by the engine fan. During operation dust and debris can buil d up on the engine si de of the radiator and restrict air flow through the fins. To remove this restriction, use compressed air or a water hose and direct the flow through the fins from the rear of the radiator toward the engine.

Tires

Inflating or servicing tires can be dangerous.

When possible, trained personnel should service and mount tires. To avoid possible death or serious injury, follow the safety precautions below.

To keep tire wear even, rotate the tires from front to rear and rear to front. It is important to keep the same size tire on each side of the loader to prevent

excessive wear on tires, chains, or other damage. If different sizes are used, tires will be turning at different speeds, causing excessive wear.

Note: The tread bars of all tires should point the same direction.

¾ BE SURE the rim is clean and free of rust. ¾ Lubricate the tire beads and rim flanges with a soap solution. Do NOT use oil

or grease.

¾ Use a clip-on tire chuck with remote hose and gauge, allowing you to stand

clear while inflating the tire.

¾ NEVER inflate beyond 35 psi (240 kPa) to seat the beads. If the beads have

not seated by the time the pressure reaches 35 psi (240 kPa), deflate the assembly, reposition the tire on the rim, lubricate both parts and re-inflate. Inflation pressure beyond 35 psi (240 kPa) with unseated beads may break the bead or rim with explosive force sufficient to cause death or serious injury.

¾ After seating the beads, adjust the inflation pressure to the recommended

operating pressure.

¾ Do NOT weld, braze or otherwise attempt to repair and use a damaged rim.

WARNING

Page 74

70 917387/BP0310

Checking Tire Pressure

Correct tire pressure should be maintained to enhance operating stability and extend tire life. Refer to the chart below for proper inflation pressures.

Heater/Air Conditioner Filters

The optional heater and heater/air conditioner include two filters: fresh air intake and recirculation air.

Refer to the Replacement Parts topic (page 52) for filter part numbers. Filters should be replaced as needed.

Fresh Air Intake Filter: Located directly behind the cover on the HVAC (heating, ventilating and air conditioning) housin g mount ed on the upper rear corner of the cab. Remove the threaded knobs on both sides of the cover to access the filter.

Recirculation Air Filters: Located behind the covers in the headliner directly above the rear window. The access, remove the screws on either side of the covers.

Important: Keeping the cab clean will reduce need for service and help ensure proper air conditioner and heater operation. Failure to do so can cause evaporator and heater core plugging, fan noise, vibration and failure.

Electrical System

Fuse Panel

The main fuse panel is located behind the cover in the operator’s compartment above the chaincase on the left side of the operator’s foot area. The loader also has a distribution panel located above and to the front of the battery in the engine compartment.

Battery

Before servicing the battery or electrical

system, be sure the battery disconnect switch is in the OFF position or disconnect the negative (ground) battery cable.

The battery on the loader is a 12-volt, wet-cell battery. The battery can be accessed on the back left rear of the machine.

The battery top must be kept clean. Clean it with an alkaline solution (ammonia or baking soda and water). After foaming has stopped, flush the battery top with clean water. If the terminals and cable connection clamps are corroded or have a build-up, disconnect the cables and clean the terminals and clamps with the same alkaline solution.

Explosive gas is produced when a battery is

in use or being charged. Keep flames and sparks away from the battery area. ALWAYS charge the battery in a well-ventilated area.

Never lay a metal object on top of a batter y, because a short circuit can result.

Battery acid is harmful on contact with skin or fabrics. If acid spills, follow these first-aid tips:

1. Immediat ely remove any clothing on whic h aci d sp il ls .

2. If acid contacts the skin, rinse the affected area with running

water for 10 to 15 minutes.

3. If acid contacts the eyes, flood the eyes with running water for 10

to 15 minutes. See a doctor at once. Never use any medication or eye drops unless prescribed by the doctor.

4. To neutralize acid spilled on the floor, use one of the following

mixtures: a. 1 pound (0.5 kg) of baking soda in 1 gallon (4 L) of water, or b. 1 pint (0.5 L) of household ammonia in 1 gallon (4 L) of water

Whenever the battery is removed, be sure to disconnect the negative (-) battery terminal connection first.

Bucket Selection

To u se the table, find the material to be loaded and its maximum density. Then multiply the volumetric rating of the attachment by the material density to determine if the attachment can safely be used. See page 88 for a listing of attachments and their ratings.

Where the material density is listed as a range (snow at 15-50 lbs./ft

, for

example), always use the maximum density (50 lbs./ft

in this example) for

making calculations. Also, see the following examples. Example 1: Clay (density of 80-100 lbs./cu. ft.) is to be hauled with a V270

model skid loader using a 70 in. dirt/construction bucket (SAE J742-rated heaped capacity of 16.9 cu. ft.). With this bucket, the V270 has a rating of 2700 lbs. Multiplying the maximum density of the material by the bucket capacity (100 x 16.9) yields a load that weighs 1690 lbs. This number is less than the machine rating and thus indicates that the loader/bucket combination is safe to use in this application.

Example 2: Granite (density of 1488-1776 kg/m

) is to be hauled with a V270 model skid loader using a 1778 mm earth and foundry bucket w/high back (SAE J742-rated heaped capacity of 0.43 m

). With this bucket, the V270 has a rating of 1225 kg. Multiplying the maximum density of the material by the bucket capacity (1776 x 0.43) yields a load that weighs 763 kg. This n umb er is less than the machine rating and thus indicates that the loader/bucket combination is safe to use in this application.
