Engine Oil & Filter
Check the oil level every 8 hours of operation. Add oil as necessary. See the engine man-
ual for oil viscosity and grade recommendations.
When checking the oil level, inspect the oil for indications of water in the oil. If there is
water present or the oil is cloudy, DO NOT start the engine. Replace the oil and oil filter,
run the engine at low idle for no more than 2 minutes and replace the oil and filter again.
CAUTION!
Operating the engine with water in the engine oil will cause
severe damage to the engine. Follow all maintenance procedures for
checking oil level and oil/filter change intervals.
IMPORTANT!
Engines on sawmills after LT30 Rev. J7.06, LT40 Rev.
J8.06, LT30HD Rev. J8.07 and LT40HD Rev. J9.07 are equipped with
a muffler rain cap to keep water out of the muffler and engine. If the
sawmill is stored outside or transported during rainy weather, the muf-
fler must be covered. The rain flap is available for previous revision
sawmills (
Change the engine oil and oil filter after the first 50 hours of operation, then every 250
hours of operation.

Cooling System
Clean the radiator fins every 8 hours of operation. Spray the radiator with water from a
hose or compressed air to clean sawdust from the radiator fins. Do not use a pressure
sprayer.
CAUTION!
Failure to keep the radiator fins clear of sawdust and/or dirt
may cause the engine to overheat resulting in damage to the engine.
3.4
Battery
Check the battery electrolyte level every 50 hours of operation. See manufacturer’s man-
ual for instructions.
DANGER!
Batteries expel explosive gases. Keep sparks, flames,
burning cigarettes, or other ignition sources away at all times. Always
wear safety goggles and a face shield when working near batteries.
Failure to do so will cause serious injury.
