• Controls should be properly tagged. Never operate the
aerial lift if it is tagged-out nor attempt to do so until it is
restored to proper operating condition and all tags have
been removed by the person(s) who installed them.
After maintenance or repairs:
• Replace all guards and covers that have been removed.
• Remove all tags, connect the battery, and perform a
function check of all operating controls.
• Consult with Manitowoc Crane Care to determine if load
testing is required after a structural repair is performed.
Lubrication
The aerial lift must be lubricated according to the
manufacturer’s recommendations for lubrication points, time
intervals, and types. Lubricate at more frequent intervals
when working under severe conditions.
Exercise care when servicing the hydraulic system of the
aerial lift, as pressurized hydraulic oil can cause serious
injury. The following precautions must be taken when
servicing the hydraulic system:
• Follow the manufacturer’s recommendations when
adding oil to the system. Mixing the wrong fluids could
destroy seals, causing component failure.
• Be certain all lines, components, and fittings are tight
before resuming operation.
Tires
Inspect the tires for nicks, cuts, embedded material, and
abnormal wear.
Ensure all lug nuts are properly torqued.
Ensure pneumatic tires are inflated to the proper pressure.
When inflating tires, use a tire gauge, clip-on inflator, and
extension hose which will permit standing clear of the tire
while inflating.
Batteries
Battery electrolyte must not be allowed to contact the skin or
eyes. If this occurs, flush the contacted area with water and
consult a doctor immediately.
When checking and maintaining batteries, exercise the
following procedures and precautions:
• Wear safety glasses when servicing batteries.
• If equipped, disconnect battery with the battery
disconnect switch before disconnecting the ground
battery cable.
• Do not break a live circuit at the battery terminal.
Disconnect the ground battery cable first when removing
a battery and connect it last when installing a battery.
• Do not short across the battery posts to check charge.
Short circuit, spark, or flame could cause battery
explosion.
• Maintain battery electrolyte at the proper level. Check
the electrolyte with a flashlight.
• If applicable to your aerial lift, check battery test indicator
on maintenance-free batteries.
• Check battery condition only with proper test equipment.
Batteries shall not be charged except in an open, well-
ventilated area that is free of flame, smoking, sparks,
and fire.
Engine
Fuel the aerial lift only with the engine turned off. Do not
smoke while fueling the aerial lift. Do not store flammable
materials on the aerial lift.
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 aerial lift equipped
with intake manifold grid heaters.
WARNING
Possible equipment damage and/or
personal injury!
Driving the aerial lift with a tire and wheel assembly under
inflated at less of its recommended pressure can cause
the wheel and/or tire to fail.
