Oil Drain Valve (If equipped)

Your lawn tractor may have a valve installed on the engine for draining oil from the crankcase. See Figure 24 .To drain the oil, insert the 12" hose (shipped loose with your unit) over the end of the valve. Place the other end in a suitable container. Push in black cap, rotate counter-clockwise and pull valve open. When oil is completely drained, push top of valve in and rotate clockwise to close.

Recommended operating tire pressure is approximately 10 p.s.i. Maximum tire pressure under any circumstance is 30 p.s.i. Equal tire pressure should be maintained on all tires.

When installing a tire to the rim, be certain rim is clean and free of rust. Lubricate both the tire and rim generously. Never inflate to over 30 p.s.i. to seat beads.

WARNING: Excessive pressure (over 30 p.s.i.) when seating beads may cause tire/ rim assembly to burst with force sufficient to cause serious injury.

SECTION 8: OFF-SEASON STORAGE

If the tractor will remain unused for more than 30 days, prepare it for storage as follows.

Clean the engine and the entire unit thoroughly.

Lubricate all pivot and linkage points. Wipe the tractor with an oiled rag to protect the surfaces.

Refer to the engine manual for correct engine storage instructions. The engine must be completely drained of fuel to prevent gum deposits from forming on essential carburetor parts, fuel lines and fuel tanks.

If your tractor is equipped with the B type battery, charge it fully. The battery loses some of its charge each day when the unit is not used. NEVER store

battery without a full charge. Recharge battery before returning to service or every two months, whichever occurs first.

When storing unit for extended periods, disconnect battery cables. Removing battery from unit is recommended.

Store unit in a clean, dry area. Do not store next to corrosive materials, such as fertilizer.

NOTE: When storing any type of power equipment in an unventilated or metal storage shed, care should be taken to rustproof the equipment. Using a light oil or silicone, coat the equipment, especially any chains, springs, bearings and cables.
