Safe Maintenance Practices
1. Perform the following steps (as applicable) before
starting a maintenance procedure:
a. Park the crane where it will not interfere with other
equipment or operations.
b. Lower all loads to the ground or otherwise secure
them against movement.
c. Lower the boom onto blocking at ground level, if
possible, or otherwise secure the boom against
dropping.
d. Move all controls to off and secure all functions
against movement by applying or engaging all
brakes, pawls, or other locking devices.
e. Stop the engine and render the starting means
inoperative.
f. Place a warning sign at the start controls alerting
other personnel that crane is being serviced and the
engine must not be started. Do not remove sign
until it is safe to return crane to service.
2. Do not attempt to maintain or repair any part of crane
while engine is running, unless absolutely necessary.
Wait for engine and machinery to cool before servicing
them.
If engine must be run, perform following steps to prevent
injury:
- Keep your clothing and all parts of your body away
from moving parts.

equipped with an approved ladder, lower them before
performing maintenance or repair procedures.

securely restrained against movement.
8. Pinch points are impossible to eliminate; watch for them
closely.
9. Pressurized air, coolant, and hydraulic oil can cause
serious injury. Make sure all air, coolant, and hydraulic
lines, fittings, and components are tight and serviceable.
Do not use your hands to check for air, coolant or
hydraulic oil leaks:
• Use a soap and water solution to check for air leaks
(apply to fittings and lines and watch for bubbles).
• Use a piece of cardboard or wood to check for
coolant and hydraulic oil leaks.
10. Relieve pressure before disconnecting air, coolant, and
hydraulic lines and fittings.

To prevent death or serious injury:
• Avoid physical contact with exhaust gases and
exhaust system components.
• Keep all flammable materials away from the exhaust
system to prevent fire.
• If necessary to service crane while engine is running,
inhibit (turn off) DPF regeneration using switch in cab
to prevent higher exhaust temperatures.
