MAINTENANCE
5.
Special attention must be given to the solution of ethylene glycol) and a
hydraulic oil during very cold weather.
corrosion inhibitor.
BEFORE
attempting any working
operations, warm up the hydraulic oil
as described in "After Starting the
Engine on Sheet
No.2-6".
6.
At the end of the work period, or
whenever the machine is to be left idle for
extended periods, prevent it from being
frozen to the ground by parking it on
wood, concrete, asphalt or mat surface.
Extreme Heat.
Like extreme cold, extreme heat requires that
precautions be taken with respect to the
cooling system, the battery and lubrication.
Protect the machine by
performing the
following recommended procedures:
1.
High temperatures necessitate the use of
lubricants which are both more viscous
and which resist deterioration at higher
operating temperatures. Refer to the
Lubrication Section and lubricate the
machine using the lubricants
recommended for the expected tempera-
tures.
Crankcase oil is particularly important
because it helps dissipate heat. Check
the oil level frequently and add oil as
required to maintain required level. Too
little oil will hinder heat dissipation.
To ensure proper coolant circulation,
drain and flush the cooling system, clean
any foreign matter from the radiator
cooling fins and through-core air
passages, replace defective hoses,
tighten hose clamps, tension the water
pump drive belt properly. eliminate any
leaks detected and fill the system with a
50%
solution of ethylene glycol.
A corrosion inhibitor is recommended.
Engine overheating due to loss of coolant
will most often be corrected by
SLOWLY
adding coolant while the engine is
running at
FAST
IDLE.
Should this fail to
correct the problem, drain and flush the
system and refill with fresh coolant
(50%
Allow the engine to cool before draining
and flushing the cooling system.
Water containing more than small
concentrations of salt or minerals should
not be used in the cooling system. Salt
facilitates corrosion and minerals deposit
on the coolant passage walls.
Both processes inhibit proper cooling.
3,
Increased evaporation rates will cause
the battery electrolyte level to fall more
rapidly during very hot weather. Check
the level frequently and add distilled
water as required to maintain the proper
level.
4.
Air circulation around the engine and
battery must not be restricted. Keep air
intake and exhaust openings clear of
leaves, paper or other foreign matter
which may restrict air flow.
5.
Keep the engine clean of dirt. grease and
other substance s which inhibit heat
dissipation.
6.
Operate engine at full throttle when
digging or tracking machine.
Run the engine only when engaged in
work operations or when traveling the
machine. Avoid prolonged periods at idle
and shut the engine down if operations
are interrupted.
W
Sandy or Dusty Work Sites
The presence of large amounts of sand or
dust at the work site can contribute to
accelerated component weather. Either
substance win act as an abrasive when
deposited on moving parts of the machine.
This problem can be alleviated by increasing
the schedule of lubrication and by servicing
breathers and fillers at more frequent
intervals. Follow the recommendations below
when operating in sand or dust on
a
regular
bases.
