Pre-Operation & Safety
Test
NEVER perform this test from the platform.
1. On a solid level surface, install outriggers and
wheels.
2. Lower platform completely. Remove fill cap on
hydraulic tank and check for proper hydraulic oil
level.
3. Activate lift function on platform controller while
pushing level sensor out of alignment. Listen for
audible tilt alarm.
4. Platform should not elevate.
DO NOT use a machine that elevates when
level sensor is off of level or tension has
been released on an outrigger. Remove
machine from service and repair before
using.
5. Release level sensor and fully elevate platform.
6. Visually inspect elevating assembly, chains and
straps. Check for missing or loose parts.
7. Partially lower platform and listen for audible
lowering alarm.
8. Turn Emergency Lowering Valve knob to check
for proper operation. To close Emergency
Lowering Valve, turn the knob until it snaps
back in.
4. Install front wheels. Pin front wheels in place
using pins provided.
BE SURE all wheels are securely attached.
Pull on wheels to check for loose pins.
5. Lower screwjacks (turn counterclockwise) until
wheels are resting on ground. Be sure
screwjacks are high enough to avoid interfer-
ence with the ground when machine is driven.
DO NOT use machine if screwjack limiting
tubes have been removed. Remove ma-
chine from service and repair before
using.
IMPORTANT: All four wheels must be in solid
contact with the ground and each outrigger indica-
tor light must be lit before the machine is operated.
