Safety

WEAR PROTECTIVE CLOTHING

10 05 2

Wear close fitting clothing and safety equipment appropriate to the job.

PROTECT AGAINST NOISE
Prolonged exposure to loud noise can cause impairment or loss of hearing.
Wear a suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises.

PRACTICE SAFE MAINTENANCE
Understand service procedure before doing work. Keep area clean and dry.
Never lubricate or service machine while it is moving. Keep hands, feet, and clothing from power-driven parts. Disengage all power and operate controls to relieve pressure. Lower equipment to the ground. Stop the engine. Remove the key. Allow machine to cool.
Securely support any machine elements that must be raised for service work.
Keep all parts in good condition and properly installed. Fix damage immediately. Replace worn or broken parts. Remove any buildup of grease, oil, or debris.
Disconnect battery ground cable (-) before making adjustments on electrical systems or welding on machine.

Safety
AVOID HIGH-PRESSURE FLUIDS
Escaping fluid under pressure can penetrate the skin causing serious injury.
Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury may call the Deere & Company Medical Department in Moline, Illinois, or other knowledgeable medical source.

FUEL
N CAUTION: Handle fuel carefully. Always stop engine before refueling. Fill fuel tank outdoors. If engine is hot, let engine cool several minutes before you add fuel. Do not smoke while you fill the fuel tank or service the fuel system. Fill fuel tank only to bottom of filler neck.
IMPORTANT: DO NOT mix oil with gasoline.
Unleaded fuel is recommended. Regular leaded gasoline with an anti-knock index of 87 or higher may be used. Avoid switch from unleaded to regular gasoline to prevent engine damage.
Use of gasohol is acceptable as long as the ethyl alcohol blend does not exceed 10 per cent. Unleaded gasohol is preferred over leaded gasohol.
Fuel tank capacity is 2-1/2 gal (9.5 L).
Lift seat. Fill fuel tank at end of each day’s operation. This helps to keep condensation out of fuel tank.

TRACTION DRIVE BELT CARE AND MAINTENANCE
1. The traction drive belt transmits power by friction and a wedging action against the sheaves. The belt is subject to normal wear through periodic heavy load and should be checked regularly. To check for normal wear, the belt and sides of sheaves should wear evenly.
2. A slight raveling of the belt covering does not indicate premature failure. Cut off the raveling if the covering peels at the lap.
3. Check for the causes of unusual belt wear as follows:
–Examine sheaves for bent or chipped sidewalls (A). Check for excessive sidewall wear (B). Damaged sheaves cause rapid belt wear. A bent sidewall (C) reduces the gripping power of the belt. Replace sheaves having any of the above defects.
–Check to be sure dirt has not lodged and packed in sheave V-groove. Loosen dirt so it will fall out when tractor is started.

INSPECT TRACTION DRIVE BELT
IMPORTANT: Never pry belt over edge of sheave. Belt cords may be damaged. Put belt in sheave groove by hand.
1. Lumpy traction drive belts can cause tractor vibration. Check belt for swells and lumps. Install only factory recommended drive belts of the proper length.
2. Whenever unusual traction drive belt failure occurs, check immediately for the cause. After correcting the cause, replace drive belt.

CLEAN TRACTION DRIVE BELT

N 50

CAUTION: Do not clean belt while tractor is

10

running.

2

1. Clean belt by wiping with a clean cloth. Immediately

wipe off any spilled oil or grease. Do not use solvents.

They soften the belt and cause the clutch to grab.

2. Do not use belt dressing. Dressings shorten belt life and often give only temporary gripping action while softening the belt and causing eventual deterioration.

2. Inspect both pivot pin assembly journals (B). Replace assembly if any irregularities are found.
3. Inspect dampening pistons (C). Replace if scored. (See Replace Dampening Pistons in this group.)
4. Shake pivot pin assembly to inspect check balls (D). If check balls do not rattle, check valve assembly is faulty. Replace valve assembly. (See Replace Check Valve Assembly in this group.)
