GENERAL OPERATING PROCEDURES - SUPPLEMENT
Operation of the Drive Lockout Override
System
To operate the Drive Lockout Override System:
Note: These procedures only apply to situations where
the boom is above 40° elevation.
1. Plan your route of travel. The surface must be
firm and as level as possible. Always avoid rough
or steep areas.
2. Level the frame before picking up the load. If
load is suspended (slung load), make sure tag
lines are secure and manned. Never let a slung
load sway, as this may lead to machine tipover or
injury to personnel.
3. With the brakes on, move the shift selector to the
Forward or Reverse position.
4. Using your left foot, press and hold down the
Drive Lockout Override Switch. The drive will
engage in first gear only and the machine may
be moved.
5. Drive the machine very slowly, while carefully
watching the terrain. Make turns smoothly and
slowly.
6. Use the service brakes to stop the machine
slowly and smoothly. Releasing the Drive
Lockout Override Foot Switch will disengage the
drive, but this will not activate the brakes.
