GENERAL CONDITION
Inspect the machine in general for wear, leakage, and damage.
AIR TANKS
Open the air tank drain cocks to blow out moisture and sediment.
FUEL FILTER
Water and sediment should be drained from the two fuel filters by opening the drain cock
at the bottom of each. See also,
“Daily Check.” on page 146
ANTI TWO-BLOCK SYSTEM
Inspect all anti-two block switches found on boom, jib, and auxiliary sheave heads for
damage. Check the freedom of counterweight attached to these switches; and also, that
counterweight is attached around correct line of hoisting cable in the proper manner.
Inspect all electrical connections and wires as well as the entire length of cable attached to
the cable reel and it’s connections for evidence of excessive wear, damage, or improper
installation. Check spring loaded cable reel for proper tension and to insure that reel is free
to rotate. Verify visual and audible warning devices by lifting each of the counter weights.
This crane is equipped with a disconnect system on the control linkages. A check of this
system should be made prior to lifting. Hoist the hook block to the boom point so that
actual contact between block and anti-two block counterweight is made. If all functions are
operating properly, winch hoisting will cease and the boom cannot be extended or lowered.
Should any of these functions continue, disconnect system is functioning improperly and a
complete system check must be made. Boom raise, boom retract, and winch down-
functions remain active and will be unaffected by anti-two block system.
When performing disconnect test, care should be taken as damage may result if
disconnect system malfunctions and the hook block is drawn into the boom point.
PUMP DISCONNECT
It is important that you check to ensure that the disconnect light on the carrier cab dash is
on after throwing the switch to engage the pumps and before starting the engine. If the
light is not on, bump the starter to jog the engine on T300-1 only, and align the pump
splines, until the light comes on before starting the engine.
Failure to follow this procedure will cause damage to the pump disconnect splines.
