Before placing any lift truck in storage, you must choose
an area which is clean, dry and free from airborne con-
taminates.
Lift trucks powered by I.C.E. must be started and run at
700 RPM until normal operating temperature is reached.
This will coat the internal engine components with a film
of oil and rid the engine of built--up condensation.
Do not shut down an engine before it reaches operat-
ing temperature.
For safety and increased usable floor area, remove the
forks and tag them with the lift truck serial number.
Prior to operating a lift truck each month, make a visual
inspection for leaks or signs of deterioration. Take correct-
ive action immediately. Also, check the fluid level in the
radiator, hydraulic tank and brake master cylinder.
All hydraulic cylinders must be cycled several times each
month to keep the seals active and to coat the interior
walls with oil. Actuate each cylinder, in both directions,
until it reaches the stops.
To protect the tilt cylinder rods, park your lift trucks with
the mast tilted fully
BACKWARD
(cylinders retracted).
When parked with the power
OFF
, actuate each control
handle to relieve hydraulic pressure.
Mast is to be stored fully lowered.
Coat any exposed portion of all cylinder rods with fresh,
high grade SAE 30 or 40 weight engine oil.
Install blocks, front and rear, at the drive wheels when
parked -- DO NOT USE THE HAND BRAKE.
HOW TO PUT BATTERIES IN STORAGE
Batteries are to be placed on a wooden pallet and stored
in a dry, moderately cool area.
Lead acid batteries will slowly “self--discharge” over a
period of time due to their chemical make--up. If the self--
discharge is left uncontrolled, excessive sulphation can
occur which is difficult to reduce and can damage the
anodes. A discharged battery with a specific gravity of
1.000 will freeze at --7.8

C (18
_
F) A fully charged battery
with a specific gravity of 1.280 will freeze at --66

(--87

F).
This “self--discharge” is due to a chemical reaction; there-
fore, that chemical reaction can be accelerated by heat
resulting in more rapid “self--discharge”. the rate of dis-
