3. Remove the ECM power fuse.
4. Remove negative battery cables.
5. Remove positive capacitor cable.
• Do not short across the capacitor posts to check charge.
Short circuit will cause capacitor terminal damage.
Spark or flame could cause capacitor explosion.
• Check capacitor charge level with proper test
equipment.
General Maintenance
Fuel the crane only with the engine turned off. Do not smoke
while fueling the crane. Do not store flammable materials on
the crane.
Be familiar with the location and use of the nearest
fire extinguisher.
Be careful when checking the engine coolant level. The fluid
may be hot and under pressure. Shut down the engine and
allow the radiator time to cool before removing the
radiator cap.
Shut down the engine and disconnect the battery before
performing maintenance. If unable to do so for the task
required, keep hands clear of the engine fan and other
moving parts while performing maintenance.
Be careful of hot surfaces and hot fluids when performing
maintenance on or around the engine.
Do not use ether to start the engine on cranes equipped with
intake manifold grid heaters.
The engine can enter into an engine exhaust cleaning mode
where the exhaust temperature can be high, make sure that
the exhaust is not pointed at materials that can melt,
burn, or explode.
TRANSPORTING THE CRANE
Before transporting the crane, check the suitability of the
proposed route with regard to the crane height, width, length,
and weight.
Check load limits of bridges on the travel route, and make
sure that they are greater than the combined weight of the
crane and transporting vehicle.
When loading or unloading the crane on a trailer or railroad
car, use a ramp capable of supporting the weight of
the crane.
Make sure that the crane is adequately secured to the
transporting vehicle.
Do not use the dead end lug (1, Figure 2-8) on the boom
nose for tying down the boom during transport. Damage to
the lug and boom can result from usage as a tie down point.
Before transporting the crane on a road or highway, first
check state and local restrictions and regulations.
Either the hook block may be reeved over the main boom
nose or the overhaul ball may be reeved over the main boom
nose or auxiliary boom nose; the other must be removed. If
the hook block or overhaul ball remains reeved on the boom,
it must be secured at the tie down on the carrier to prevent
swinging.
When using hookblock tie downs, excessive loading can be
applied by pulling the cable too tight, particularly when
reeved with multiple part lines. When the cable is hooked
into the hookblock tie down, the cable should be merely
“snugged-up” with adequate slack provided at the center line
of sheave to anchor point. Do not draw cable taut. Care must
be exercised anytime any crane function is being performed
while the cable is hooked into the hookblock tie down.
TRAVEL OPERATION
O n l y t h e c r a n e o p e r a t o r s h a l l o c c u p y t h e c r a n e
when traveling.
When traveling, the boom should be completely retracted
and lowered to the travel position and the turntable pin swing
lock, if equipped, should be engaged. If equipped with boom
rest, lower the boom into the boom rest and engage the
turntable lock.
Strictly adhere to the guidelines and restrictions in the Load
Chart for pick and carry operations.
GRT cranes are manufactured without an axle suspension
system. Traveling at high speeds, especially on rough
ground, may create a bouncing effect that can result in loss
of control. If bouncing occurs, reduce travel speed.
