ENGINE
LUBRICATION
Check the engine oil level daily.
GASOLINE AND LPG POWERED ENGINES
Gasoline and LPG powered engines should be
lubricated with SAE--SE/SF rated engine oil.
Change the engine oil and oil filter after every 50
hours of operation. Change the engine oil more
frequently if the environment is extremely dusty.
The following oil grades are recommended for
engines operating in the ambient temperatures
listed.

The engine oil capacity for the Continental TM27
engine (machines below serial number 001424) is
7 qt (6.6 L) with filter.
The engine oil capacity for the Gas/LPG GM
engine (machines serial number 001424 and
above) is 5 qt (4.7 L) with filter. On GM engines,
the oil fill is under the breather cap.
DIESEL POWERED ENGINES
Change the engine oil and oil filter after every 50
hours of operation. Change the engine oil more
frequently if the environment is extremely dusty.
The following oil grades are recommended for
engines operating in the ambient temperatures
listed.

The engine oil capacity for the Diesel Continental
TMD27 engine (machines below serial number
001424) is 7 qt (6.6 L) with filter.
The engine oil capacity for the Diesel Perkins
engine (machines serial number 001424 --
001505) is 11 qt (10.4 L) with filter.
The engine oil capacity for the Diesel Cat engine
(machines serial number 001508 and above) is
10.6 qt (10.0 L) with filter.
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.
Use soft, clean water mixed with permanent-type,
ethylene glycol antifreeze in a one-to-one ratio.
Deposits of sludge, scale, and rust prevent normal
heat transfer. Flush the radiator and the cooling
system after every 800 hours of operation using a
dependable 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 hose. Clean the radiator
exterior after every 50 hours of operation.
Blow all dust, which may have collected on the
radiator, in through the grill and radiator fins,
opposite the direction of normal air flow. This
should be done only after the radiator has cooled,
to avoid cracking.
FOR SAFETY: When Servicing Machine,
Wear Eye And Ear Protection When
Using Pressurized Air Or Water.
