boom extension.
Install and secure all pins properly.
Control movement of the boom extension at all times.
Do not remove right side boom nose pins unless boom
extension is properly pinned and secured on front and rear
stowage brackets.
Do not remove the pins from the front stowage bracket
unless the boom extension is pinned to the right side of the
boom nose.
Properly inspect, maintain, and adjust boom extension

When assembling and disassembling boom extension
sections, use blocking to adequately support each section
and to provide proper alignment.
Stay outside of boom extension sections and lattice work.
Watch for falling or flying pins when they are being removed.
PARKING AND SECURING
When parking on a grade, apply the parking brake and chock
the wheels.
Section 4 of this manual provides instructions for parking and
securing a crane when it is to be left unattended. These
instructions are intended to allow the crane to be placed in
the most stable and secure position. However, Grove
recognizes that certain jobsite conditions may not permit the
boom and boom extension of a crane to be fully lowered to
the ground. When a qualified person at a jobsite determines
that it is not practical to lower the boom to the ground, we
recommend the following additional instructions be followed:
• The crane should be left in the smallest, most stable,
valid operational configuration that the job site
practically allows.
• The crane can not be left running, with a load on the
hook, or with the jib deployed, or in wind conditions in
excess of allowed values.
• The boom should be retracted as far as is practical, the
crane configured in as stable a configuration as possible
(boom angle, superstructure orientation, boom
extension angle, etc.)
• In high winds the boom and boom extension should be
lowered, or secured. Changing weather conditions
including, but not limited to, wind, ice accumulation,
precipitation, flooding, lightning, etc., should be
considered when determining the location and
configuration of a crane when it is to be left unattended.
SHUT-DOWN
Use the following steps when shutting down the crane:
• Engage the parking brake.
• Fully retract and lower the boom.
• Engage the swing lock pin or 360 degree swing lock (if
equipped).
• Place crane function power switch to OFF (if equipped).
• Place controls in neutral position.
• Shut down the engine and remove the ignition key.
• Wait a minimum of two minutes and then turn the battery
disconnect switch to the OFF position.
• Chock the wheels, if not on outriggers.
• Lock the operator’s cab (if applicable) and install vandal
guards, if used.
COLD WEATHER OPERATION
Cold weather operation requires additional caution on the
part of the operator.
Check operating procedures in this manual for cold weather
starting.
Don’t touch metal surfaces that could freeze you to them.
Clean the crane of all ice and snow.
Allow at least 30 minutes of engine run time for hydraulic oil
to warm up.
Plastic components (battery casings, heater controls, dash
controls, etc.) are extremely brittle in extreme cold. Use
