5.1PERIODIC MAINTENANCE

5.1.1Check engine oil level:

Service Interval: Daily

a)Stop engine and wait for all moving parts to stop. Make sure unit is on a level surface.

b)Check with engine cold.

c)Raise hopper.

d)Clean area around dipstick. Remove dipstick and wipe oil off. Reinsert the dipstick and push it all the way down into the tube. Remove the dipstick and read the oil level.

e)If the oil level is low, wipe off the area around the oil fill cap, remove cap and fill to the “FULL” mark on the dipstick. Use oil as specified in Engine Owner’s Manual. DO NOT overfill.

IMPORTANT: DO NOT operate the engine with the oil level below the “LOW” (or “ADD”) mark on the dipstick, or over the “FULL” mark.

5.1.2Check battery charge:

Service Interval: Monthly

Allowing batteries to stand for an extended period of time without recharging them will result in reduced performance and service life. To preserve optimum battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.4 volts.

Note: To prevent damage due to freezing, battery should be fully charged before putting away for winter storage.
