Protecting Yourself and Those Around You

This is a high-powered machine, with moving parts operating with high energy. You must operate the machine safely. Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area. Always take the following precautions when using this machine:

• Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and

themselves.

• Always wear protective goggles or safety glasses with side shields while using the backhoe to protect your eyes from possible

thrown debris.

• Avoid wearing loose clothing or jewelry, which can catch on moving parts.

• We recommend wearing gloves while using the backhoe. Be sure your gloves fit properly and do not have loose cuffs or

drawstrings.

• Wear shoes with non-slip treads when using your backhoe. If you have safety shoes, we recommend wearing them. Do not

use the machine while barefoot or wearing open sandals.

• Wear long pants while operating the backhoe.

• Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing.

• Keep bystanders at least 100 feet away from your work area at all times. Lower the bucket and stop the engine when another

person or pet approaches.

• Position a barricade around the work area.

• Never allow a person to work under a raised bucket.

• Never lift a

erson with the backhoe.

Safety for Children and Pets

Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the machine and the digging activity. precautions:

Never

assume that children will remain where you last saw them. Always follow these

• Keep children and pets at least 100 feet from the working area and ensure they are under the watchful care of a responsible

adult.

• Be alert and turn the machine off if children or pets enter the work area.

• Never allow children to operate the backhoe.

Safety with Gasoline - Powered Machines

Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or explosion. Never overlook the hazards of gasoline. Always follow these precautions:

• Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine contains carbon

monoxide, which is an odorless, tasteless, and deadly poisonous gas.

• Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat and open

flame, and out of the reach of children.

• Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.

• Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Don't handle gasoline if you or

anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the fuel tank Cap and fuel container cap securely.

4 DR

TOWABLE BACKHOE

• If you spill gasoline, do not attempt to start the engine. Move the machine away from the area of the spill and avoid creating

any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly dispose of the waste.

• Allow the engine to cool completely before storing in any enclosure. Never store a machine that has gas in the tank, or a fuel

container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.

• Never make adjustments or repairs with the engine running. Shut down the engine, disconnect the spark plug wire, keeping

it away from the spark plug to prevent accidental starting, wait 5 minutes before making adjustments or repairs.

• Never tamper with the engine’s governor setting. The governor controls the maximum safe operation speed and protects

the engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the machine. If required, see your authorized dealer for engine governor adjustments.

• Keep combustible substances away from the engine when it is hot.

• Never cover the machine while the muffler is still hot.

• Do not operate the engine with the air cleaner or the carburetor air intake cover removed. Removal of such parts could

create a fire hazard. Do not use flammable solutions to clean the air filter.

• The muffler and engine become very hot and can cause a severe burn; do not touch.

Hydraulic Safety

High fluid pressures are developed in hydraulic machines. Pressurized hydraulic fluid escaping through a pin hole opening can puncture skin and cause severe blood poisoning. Therefore, the following Instructions should be heeded at all times.

• Do not operate the unit with frayed, kinked, cracked or damaged hoses, fittings, or tubing. Stop the engine, wait 5 minutes and

relieve hydraulic system pressure before changing or adjusting fittings, hoses, tubing, or other system components.

• Do not change any backhoe relief valve settings. They are set at the factory for best backhoe performance and safety.

• Do not check for leaks with your hand. Leaks can be located by passing cardboard or wood over the suspected area: Look for

discoloration. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if proper medical treatment is not administered immediately.

• Alwa

s wear safety glasses to protect your eyes from hydraulic fluid.

Safety When Digging Near Utilities

Call 811 before you begin any digging project. A new, federally-mandated national "Call Before You Dig" number, 811 was created to help protect you from unintentionally hitting underground utilities while working on digging projects. Every digging job requires a call. If you hit an underground utility line while digging, you can harm yourself or those around you, disrupt service and potentially be responsible for fines and repair costs.

• There may be buried power, gas, and/or telephone lines in the work area. Electric shock, death, or explosion may occur.

• Have the property or work area marked for buried lines and do not dig in marked areas.

• There may also be overhead power lines in the work area. electric shock or death may occur if a power line is touched by the

backhoe.

• Survey and mark the area where there are overhead power lines and dig with caution under power lines to ensure that you do

not touch them with the backhoe.

Towing

o not tow the backhoe near the

edge of a ditch or excavation.

• ALWAYS check before towing to make certain your backhoe is correctly and securely attached to the towing vehicle. Be sure

that the ball hitch you are using is the proper size for the hitch coupler on the backhoe. Be sure the safety chains are properly hooked to the vehicle leaving enough slack for turning.

• ALWAYS install the swing and boom transport hitch pins and lynch pins before transporting the backhoe.

• ALWAYS use accessory lights and devices when transporting on a road or highway to warn operators of other vehicles. Check

your local government regulations for DOT information.

• ALWAYS allow for added length of the backhoe when turning, parking, crossing intersections, and in all driving situations.

• ALWAYS be careful when backing up. You could jackknife your backhoe if care is not taken.

• NEVER exceed 45 mph. when towing your backhoe. Obey all state and local regulations when towing on state and local roads

and highways. Adjust your speed for terrain and conditions, as needed. Be extra cautious when towing over rough terrain, especially over a railroad crossing.

• NEVER allow anyone to sit or ride on your backhoe.

• NEVER carry any cargo on your backhoe.

• Do travel slowly over rough terrain, on hillsides, and around curves to prevent tipping.

Adding Hydraulic Fluid

• You must add hydraulic fluid before using the backhoe. This machine

is shipped without hydraulic fluid in the hydraulic tank. Fill the hydraulic tank slowly, checking the level frequently to avoid overfilling.

• To get an accurate reading when checking the hydraulic fluid level:

- the machine should be on a level surface.

- the dipstick should be screwed on to ensure an accurate fluid level reading.

1-3/4"

TIP: Check the Fluid level by removing the Hydraulic Fluid Filler Cap and wiping the steel rod of the Dipstick with a clean Rag or Paper Towel. Reinsert and tighten the Cap to the proper position (1-3/4" from the bottom of the Cap to the top of the Tank) (Figure 4). Remove the Cap and lay the Steel Rod onto a dry Paper Towel or Rag and read the level by the wet mark that is transferred from the Steel Rod to the Rag.

1. Remove the Hydraulic Fluid Fill Cap Dipstick and fill the Hydraulic Tank with

the recommended fluid (see the “Specifications” section, page 2).

NOTE: The tank is full when the fluid level is within the recommended level on the

Dipstick. The recommended level is in the middle (2-3/8" up from the bottom) of the Steel Rod. Do not deviate more than 1/2" up or down from that point. If the fluid level is not within this range, fluid must be added or removed to bring it within that range.

NOTE: The total hydraulic system fluid capacity is 9.4 gallons. The operator should

initially only need to add about 8 gallons before checking the level because some fluid has already been added to the Cylinders.

Digging with the Backhoe

It is not difficult (but it does take practice) to become an efficient operator. A control lever operating decal is located just under the control levers. Study this decal; it will help you become familiar with the controls. See Figures 6 and 7 for control locations and functions.

Smooth, light handling of the controls will result in the most efficient machine operation. Operate the backhoe control levers to become familiar with their speed and movements. The engine speed will determine the speed of the cylinder operation. Slower Engine speed means slower Boom, Swing Arm and Bucket movements.

Swing the boom several times to practice controlling the speed of the swing.

Best results are obtained by digging near the center of the swing arc so material can be dumped to either side.

To avoid damage to the Backhoe, do not slam the swing unit into the end of the swing cylinder stroke.

Figure 17

Bucket Digging

Never dig with the Backhoe unless all Stabilizers are down and pinned securely.

Figure 18

18" to 24"

1. Lower the Bucket to the digging area with the Bucket pivot 18" to 24"

forward of the Boom/Crowd Arm pivot (Figure 18).

NOTE: It is important for the Bucket to be in the proper position for digging efficiency. The Bucket will not dig as well if you attempt to dig with the Bucket in the wrong position, tilted too far forward or too far back (Figure 19).

2. Using down pressure on the Bucket bottom, force the Bucket into the

ground.

3. With the Bucket in the ground, simultaneously retract the Crowd Arm and

load the Bucket until it is full (Figure 18).

4. If the Bucket stalls, raise the Boom slightly and continue to dig until the

Bucket is full.

5. Raise the Bucket to the top of the trench and dump it on the spoil pile.

6. When lifting the loaded Bucket high, continue rolling the Bucket in as it is

being raised to prevent spilling the contents.

NOTE: With a little practice, raising, swinging, and dumping can be accomplished in one smooth operation.

Crowd Arm Digging

1. Lower the Bucket to the digging area with the Bucket pivot 18" to 24"

forward of the Boom/Crowd Arm pivot.

2. Rotate the Bucket until the cutting edge teeth are flat on the ground.

12. Remove the Hitch Pins of the Rear Stabilizers and rotate them into their

upright position until the holes are aligned (Figure 27).

13. Reinstall Hitch Pins into the Rear Stabilizers and secure with the Lynch Pins.

Making sure the backhoe is securely attached to the vehicle is the responsibility of the owner/operator. Failure to securely attach the backhoe can cause loss of control of the vehicle or the backhoe being separated from the towing vehicle, resulting in serious injury or death. ALWAYS use accessory lights and devices when transporting on a road or highway to warn operators of other vehicles. Check your local government regulations.

14. Close the Latch Assembly on the Tow Hitch Assembly to lock the Tow Hitch

Assembly onto the Tow Ball (Figure 28). Attach the towing Safety Chains to the tow vehicle ensuring there is enough slack for turning.

15. Make sure the hitch coupler is properly and securely attached to the tow ball.

16. Insert the Locking Pin into the hole of the Latch Assembly to lock it in the

closed position (Figure 29).

17. For extra safety and security, you may want to purchase a lock to install into

the hole of the latch assembly.

Hitch Coupler Adjustment Check

1. Place the proper size ball in the socket of the coupler and close the latch

assembly (Figure 30). Verify that the locking trigger is properly engaged in its detent.

2. Pull on the ball and/or coupler, trying to remove the ball from the socket. If

the ball moves more than 1/16" in the coupler’s socket, the clamp requires adjustment. Follow the proper adjustment procedure in the following steps.

Tools and Supplies Needed:

• 14mm Wrench

• Rags and approved waste oil Container

1. Drain the used oil into an approved container by removing the Engine Drain Plug with a 14mm Wrench.

2. Replace the Drain Plug and go to Chapter 2 for instructions on adding Oil to the Engine.

Greasing the Backhoe

Economical and efficient operation of any machine is dependant upon regular and proper lubrication of all moving parts with a quality lubricant. All parts provided with grease fittings should be lubricated with a good quality chassis lube type grease. If any grease fittings are missing, replace them immediately.

NOTE: Moving the Swivel, Boom, Crowd Arm and Bucket to different positions first will provide better access for some fittings. You will

need to remove the Foot Plate to access the rear Grease Fitting on the Swing Cylinder.

Tools and Supplies Needed:

• Grease Gun (general purpose grease)

• Rags

3. Wipe any grease or dirt from all

Grease Fittings with a rag.

4. Grease the Backhoe at all fifteen

Grease Fittings (Figure 32) until you notice grease escaping from the joint.

5. Wipe off any excess grease with a

rag.

• 9/16" Wrench

• Filter Wrench

• Clean Waste Fluid Container (10 Gallon capacity)

• Hydraulic Fluid (see spec sheet on page 9)

• New Hydraulic Fluid Filter

• Safety Glasses

• Clean Rags

NOTE: If the Hydraulic Fluid needs to be changed also, drain the Fluid first (see

“Changing the Hydraulic Fluid”).

1. Place a Waste Fluid Container under Filter and Connections.

2. Set the Front Stabilizers to their highest position.

3. Lower the Tongue end of the Backhoe some to help reduce Fluid loss when

changing the Filter.

NOTE: Be careful when lowering the tongue end of the Backhoe that hydraulic fluid

does not escape from the Hydraulic Fluid Fill Cap.

4. Use a 9/16" wrench to remove the four Bolts, Lock Washers and Washers

from the Foot Plate and remove the Foot Plate (Figure 33).

5. Apply a thin coat of fresh hydraulic fluid to the Rubber Seal of the new

Hydraulic Fluid Filter.
