deceleration.

DANGER

POTENTIAL HAZARD ♦ Mowing on wet grass or steep slopes can

cause sliding and loss of control. WHAT CAN HAPPEN ♦ Wheels dropping over edges, ditches,

steep banks, or water can cause

rollovers, which may result in serious

injury, death or drowning. HOW TO AVOID THE HAZARD

♦ Do not mow slopes when grass is wet. ♦ Do not mow near drop-offs or near water. ♦ Do not mow slopes greater than 15

degrees.

♦ Reduce speed and use extreme caution

on slopes.

♦ Avoid sudden turns or rapid speed

changes.

• See inside the back cover to determine the approximate slope angle of the area to be mowed.

• Use a walk behind mower and/or a hand trimmer near drop- offs, ditches, steep banks or water. This area can be dangerous, see Figure 1.

FIGURE 1

• Progressively greater care is needed as the slope increases.

• Always avoid sudden starting or stopping on a slope. If tires lose traction,

disengage the blades and proceed slowly off the slope.

• Avoid sudden stops when mowing downhill. Tractor may tip forwards.

• Be aware that loss of traction may occur going uphill. Weight transfer to the

rear wheels may cause drive wheels to slip and cause loss of braking and steering.

• Watch for ditches, holes, rocks, dips, and r ises t hat change the operating angle, as rough terrain could overtur n the machine.

• Remove or mark obstacles such as rocks, t r ee lim bs, etc. from the mowing area. Tall grass can hide obstacles.

• Use extreme care with attachments. These can change t he st ability of the machine and cause loss of control.

• Follow the manufacturer’s recommendations for wheel weights or counterweights to improve stability.

1.4.5 A Rollover Protection System (roll bar) is installed on t he unit.

DANGER

POTENTIAL HAZARD ♦ There is no rollover protection when the

roll bar is down. WHAT CAN HAPPEN ♦ Wheels dropping over edges, ditches,

steep banks, or water can cause

rollovers, which may result in serious

injury, death or drowning. HOW TO AVOID THE HAZARD

♦ Keep the roll bar in the raised and locked

position and use seat belt.

♦ Lower the roll bar only when absolutely

necessary.

♦ Do not wear seat belt when the roll bar is

down.

♦ Drive slowly and carefully.

♦ Raise the roll bar as soon as clearance

permits.

• Be certain that the seat belt can be released q u ickly if the machine is driven or rolls into ponds of water.

• Check carefully for overhead clearances (i. e. branches, doorways, and electrical wires) before driving under any objects and do not contact them.

1.4.6 Use EXTREME caution when backing up. LOOK BEHI ND YOU!

1.4.7 Stop the blades when crossing surfaces other than grass and when transporting the mower to and from the area to be mowed.

1.4.8 Never operate the mower with damaged guards, shields, or covers. Always have safety shields, guards, switches, and other devices in place and in proper working condition.

1.4.9 DO NOT change the engine governor settings or overspeed the engine. Operating an engine at excessive speed may increase the hazard of personal injury.

1.4.10 Disengage PTO before starting engine.

POTENTIAL HAZARD ♦ This unit does not have proper turn

signals, lights, reflective markings, or a slow moving vehicle emblem. These items are required to drive on a public street or roadway.

WHAT CAN HAPPEN ♦ Driving on a street or roadway without

such equipment is dangerous and can lead to accidents causing personal injury.

♦ Driving on a street or roadway without

such equipment may also be a violation of State laws and the operator may be subject to traff ic tickets and/or fines.

: Use a heavy-duty trailer or truck to tr anspor t the machine.

CAUTION

HOW TO AVOID THE HAZARD

♦ Do not drive a unit on a public street or

roadway.

WARNING

POTENTIAL HAZARD ♦ Loading a unit on a trailer or truck

increases the possibility of tip-over. WHAT CAN HAPPEN ♦ Tip-over of the unit could cause serious

injury or death. HOW TO AVOID THE HAZARD

♦ Use extreme caution when operating a

unit on a ramp.

♦ Use only a single, full width ramp; DO

NOT use individual ramps for each side of the unit.

♦ If individual ramps must be used, use

enough ramps to create an unbroken ramp surface wider than the unit.

♦ DO NOT exceed a 15° angle between

ramp and ground or between ramp and trailer or truck.

♦ Avoid sudden acceleration while driving

unit on a ramp.

3.4.2 Loading a Unit: Use extreme caution when loading units on tr ailer s or t rucks. One full width ramp is required. I f it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp.

Ramp should be long enough so that the angles between the ramp and the ground and the ramp and the trailer or tr uck do not exceed 15°. A steeper angle may cause mower deck components to get caught as t he unit moves from ramp to trailer or truck. St eeper angles may also cause the unit to tip. If loading on or near a slope, position the trailer or tr uck so it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp ang le. The trailer or truck should be as level as possible.

DO NOT attempt to tur n t he unit while on the ramp, you may lose control and drive off the side.

Avoid sudden acceleration when driving on a ramp.

5. WASTE DISPOSAL

5.1 MOTOR OIL DISPOSAL

Engine oil and hydraulic oil are both pollutants to the environment. Dispose of used oil at

a certified recycling center or accor ding to your state and local regulations.

5.2 BATTERY DISPOSAL

DANGER

POTENTIAL HAZARD ♦ Battery electrolyte contains sulfuric acid,

which is poisonous and can cause severe

burns WHAT CAN HAPPEN ♦ Swallowing electrolyte can be fatal or if it

touches skin can cause severe burns. HOW TO AVOID THE HAZARD

♦ Wear safety glasses to shield eyes, and

rubber gloves to protect skin and clothing when handling electrolyte.

♦ Do not swallow electrolyte.

Federal law states that batteries should not be placed in the garbage. Management and disposal practices must be within relevant federal, state, or local laws.

If a battery is being replaced or if the unit containing the battery is no longer operating and is being scrapped, take the battery to a local certified recycling center. If no local recycling is available return the battery to any certified battery reseller.

6. TROUBLE SHOOTING

6.1 MOWER PULLS LEFT OR RIGHT (W/LEVERS FULLY FORWARD).

a) Refer to Tracking Adjustm ent Section 4.2.5. b) Check air pressure in drive tires.

AT101 (Bar Lug) drive tires should be inf lat ed t o 9 psi ( 62 kpa). Turf Mate drive tires should be inflated t o 13 psi ( 90 kpa). Semi-pneumatic casters do not requir e inflation.

6.2 MOWER CUTS UNEVENLY.

a) Check air pressure in drive tires.

AT101 (Bar Lug) drive tires should be inf lat ed t o 9 psi ( 62 kpa). Turf Mate drive tires should be inflated t o 13 psi ( 90 kpa). Semi-pneumatic casters do not requir e inflation. A more uniform cutting height may be obtained with higher tire pressure on rough

terrain. A lower tire pressure provides more flotation.

b) Check deck leveling (See Adjustments in Deck Manual).

Note: The front of the mower deck will be approximately 1/4” lower than the back of the mower deck. This is the “ r ake” of the deck.

c) Check the distance from the bottom edge of the deck skirt to t he t ip of each

blade. Measurement should be consistent between all blade tips.

6.3 ENGINE WILL NOT START.

a) Make sure the battery has a full charge. See section 4.1.3 for charging

instructions. b) Be sure the throttle control is in the correct position. See sect ion 3. 3. 2. c) Make sure there is fuel in the fuel tank. d) Make sure the parking brake is set and mo t ion cont r ol levers in the neutral

position. e) Check that the PTO is disengaged. f) Check for loose or faulty wiring connections. g) Check for corrosion at all wiring connections. Even minor corrosion may cause a

faulty connection. Clean connector terminals t hor oughly with electrical contact

cleaner, apply dielectric grease and reconnect.

NOTE: When disconnecting electrical connectors DO NOT pull on the

wires to separate the connectors.

NOTE: After carefully checking the above steps, attempt to start the

engine. If it does not start, cont act your authorized Exmark service dealer.

IMPORTANT: It is essential that all operator safety mechanisms be

connected and in proper operating condition prior to mower use.

When a problem occur s , do not overlook the simple causes. For example:

starting problems could be caused by an empty fuel tank.

The following table lists some of t he common causes of trouble. Do not att em pt

to service or replace major items or any item s t hat call for special timing of

adjustments procedures (such as valves, governor, etc. ) . Have this work done

by your Engine Service Dealer.
