Secure Hook Block
1. If cable and hook block are lying on the
ground after completing these emergency pro-
cedures, tighten cable and install wood block
on winch to retain tension on cable. Remove
cable from hook block socket and secure
cable to vehicle.
Weight of the hook block is
approximately 235 lb (107 kg).
Use adequate hoist and sling to
lift hook block. Do not lift over
personnel or let personnel walk
underneath suspended load.
Failure to follow this procedure
could cause DEATH or serious
injury.
2. Using hoist and sling, lift hook block to tool
box for carrying purposes.
Unus ual Operating ConditionS
Special problems in maintenance and operation
are caused by unusual conditions such as ex-
tremes in heat, cold, humidity, high altitude, salt
water and dusty or sandy work sites. When
operating under such conditions, special precau-
tions must be taken to prevent vehicle damage,
minimize wear and avoid component deteriora-
tion.
Extreme Cold
In periods of extreme cold, problems of freeze
damage, adequate lubrication and battery failure
may become particularly troublesome. With the
onset of very cold weather, it is advisable to
“winterize” the LRT 110 Crane by servicing the
cooling system and switching to the lubricant
recommended for cold weather usage. Follow
recommendations in this manual when operating
the LRT 110 Crane under very extreme condi-
tions.

Prevent freeze damage. To prevent freeze
damage to the cooling system and cracking of
engine block or head, drain and flush cooling
system. Clean radiator exterior, making
certain all air passages through core and
cooling fins are free of foreign matter.
CAUTION
Never use a chromate-base corro-
sion inhibitor when coolant
contains ethylene glycol. Use
only nonchromate-base inhib-
itors. Chromate-base inhibitors
reacting with ethylene glycol can
produce chromium hydroxide,
commonly known as “green
slime.” This substance reduces
the heat transfer rate and can
cause serious engine overheating.
Refill cooling system. Add an antifreeze so-
lution as recommended in the amount and
strength appropriate to anticipated tempera-
tures. A corrosion inhibitor is recommended.
Inspect clamps, radiator hoses and radiator.
Replace or repair any cooling system compo-
nent found to be defective.
Condensation in fuel tank contaminates the
fuel supply with water. This can freeze in
fuel lines and block fuel flow to engine. To
minimize this possibility, keep tank as full as
possible during cold weather. This may entail
refilling tank more frequently than usual, but
the inconvenience is small compared to
clearing a blocked fuel line.
Check and drain the fuel/water separator. If
water is found in fuel tank, drain tank and
refill it with uncontaminated fuel.
