Boom
Before extending the boom, ensure the large access cover
on top of the boom base section is installed.
Cold Weather Operation
The following recommendations are for operating Grove
cranes in very low (i.e. freezing) temperatures.
Use particular care to ensure that cranes being operated in
very cold temperatures are operated and maintained in
accordance with the procedures as provided by Manitowoc
Crane Care. Cranes should have appropriate hydraulic oil,
lubricants, and other auxiliary items required for operation in
sub-zero temperatures. Individual crane functions should be
operated to ensure they are sufficiently warmed prior to
performing a lift.
Operation of cranes at full rated capacities in temperatures
between 0°C and -40°C (+32°F and -40°F) or lower shall be
accomplished only by competent operators who possess the
skill, experience, and dexterity to ensure smooth operation.
Shock loading shall be avoided. See Section 5 of this manual
for more detailed information on operation of cranes down to
-40°F.
Operation Below -40°C (-40°F)
For crane operation below -40°C (-40°F), capacities shall be
derated 3.67% of the capacities shown on the load chart for
each 1°C below -40°C (1.8°F below -40°F).
Engine Operation
Start-up and shutdown procedures for most diesel engines
are generally the same. Therefore, the following procedures
can be applied, except where specific differences are noted.
(Refer to the applicable engine manufacturer’s manual for
detailed procedures).
Start-Up Procedure
Make an under-the-hood inspection for fuel, oil, and coolant
leaks, worn drive belts, and trash build-up.
Use the correct grade of oil for the prevailing temperature in
the crankcase to prevent hard cranking. Diesel fuel should
have a pour point of 5°C (10°F) less than the lowest
expected temperature. In case of an emergency, white
kerosene can be added to the fuel to bring the pour point
down to the required temperature. This will prevent clogging
of filters and small passages by wax crystals. The addition of
kerosene is NOT recommended for general use.
Ensure Battery Disconnect Switch handle (1) (Figure 3-6) is
in the ON position (handle shown in the OFF position)
DANGER
Diesel engine exhaust can be harmful to your health. Only
operate the engine in a well ventilated area or vent
exhaust outside.
CAUTION
Never crank engine for more than 30 seconds during an
attempted start. If engine does not start after 30 seconds,
allow starter motor to cool for two minutes before
attempting another start.
CAUTION
If engine does not start after four attempts, correct
malfunction before attempting another start.
