(continued)

OPERATING PROCEDURE
1. Moving Lift to Work Area
(No Load)
The lift is normally moved to the job site
by rolling on its four caster wheels. Note:
Do not pull by the load lifting cable.
IMPORTANT Before tilting unit to reclined
position, the carriage must be in the down
position below the red arrows, and ensure
that the safety latch is engaged.
To Tilt the unit into position for transport;
from a squatting position, grasp the legs
just past the front casters and while keep-
ing your back straight, lift upwards to a
standing position while someone supports
the unit from behind. The unit is now
ready to transport.
2. Moving Lift in Work Area
(With Load)
Although it is best to move the unit to the
job site unloaded, light loads may be
transported as long as the stabilizer legs
are installed and the unit is rolled on the
eight caster wheels and on a level sur-
face. Always have the load in the lowest
possible position before moving the unit.
If it is necessary to move the unit with an
elevated load:
Make sure the area is clear of obstruc-
tions
Keep personnel away from the load
and behind the operator’s position.
Move the unit slowly, avoiding sudden
jerky starts and stops
Make sure the load is secure and prop-
erly balanced Note load capacity at
given centers below.
Make sure the stabilizer legs are in-
stalled and locked into position.

CAUTION
Always use proper lifting techniques.
CAUTION
If a load is being transported,
it should be secured to the fork
to avoid shifting.
WARNING
Moving the unit with elevated loads
should be contained to short
distances; i.e., 10-15 feet/4-5 meters.
WARNING
Do not extend load centers beyond
fork ends by modifying the lift.
Lift may become unstable.
