SECTION7-- SERVICE
ReplacingFuse
The electric starter circuit and battery are protected by a 40 ampere fuse. If the fuse burns out, the electric starter will not
operate. If the unit fails to start with the electric starter, perform the following steps to check the fuse inside the battery housing:
1. Open the battery cover as described in Replacing Battery. See Fig. 7-5.
2. Remove fuse from socket and inspect as shown in Fig. 7-8. If it is burned out, replace with standard automotive 40 ampere fuse.
Off-SeasonStorage
The following steps should be taken to prepare your lawn mower for storage.
Clean and lubricate mower thoroughly as described in the lubrication instructions.
Do not use a pressure washer or garden hose to clean your unit.
Coat mower's cutting blade with chassis grease to prevent rusting.
Refer to engine manual for correct engine storage instructions.
Store mower in a dry, clean area. Do not store next to corrosive materials, such as fertilizer.
When storing any type of power equipment in a poorly ventilated or metal storage shed, care should be taken to rust-proof the equipment. Using a light oil or silicone, coat the equipment, especially cables and all moving parts of your lawn
mower before storage.
Battery
The battery must be stored with a full charge. Extended storage of a discharged battery will reduce life and capacity of the
battery.
