ENGINE LUBRICATION
Check the engine oil level daily. Change the engine
oil and oil filter after every 50 hours of operation.
GASOLINE AND LPG ENGINES
Gasoline and LPG powered engines should be
lubricated with SAE---SE/SF rated engine oil.
The following SAE---SE/SF rated oil grades are
recommended for engines during changing seasonal
temperatures:

COOLING SYSTEM
Maintaining cooling system efficiency is important.
Engine temperatures must be brought up to and
maintained within the satisfactory range for efficient
operation. However, the engine must be kept from
overheating in order to prevent damage to the
valves, pistons, and bearings. Check the radiator
coolant level after every 100 hours of operation. Fill
the cooling system through the coolant overflow tank
--- not through the radiator.
Use soft, clean water mixed with permanent-type,
ethylene glycol antifreeze in a one-to-one ratio to fill
the cooling system. Deposits of sludge, scale, and
rust prevent normal heat transfer. Flush the radiator
and the cooling system after every
800 hours of operation, with a cleaning compound.
Follow the mixing procedure recommended by the
compound manufacturer. This is important because
of the difference in concentration and composition of
the cleaning compounds. After cleaning, flush the
system with clean water.
Whenever a cooling system is badly rust-clogged, as
indicated by overflow loss or abnormally high
operating temperatures, corrective cleaning by
reverse flow flushing will most effectively remove the
heavy deposits of sludge, rust, and scale. The
reverse flow flushing should be performed
immediately after draining the cleaning solution.
Flush the radiator first, then the engine, to allow the
engine to cool as much as possible.
Engine overheating may also be caused by dirty
radiator fins. The exterior fins of the radiator can be
cleaned with an air or water hose. Check the radiator
core exterior daily for debris.
WARNING: Air or water under pressure.
Severe eye or ear injury can result. Wear
eye and ear protection.
