3.3 Pre-Operation Inspection
NOTE: Carefully read, understand and follow all
safety rules, operating instructions, labels and the
Scaffold Industry Association's MANUAL OF RESPON-
SIBILITIES. Perform the following steps each day
before use.
1. Open modules and inspect for damage, oil leaks or
missing parts.
2. Check the hydraulic oil level sight gauge on the
hydraulic tank with the platform fully lowered. Add
ISO #46 hydraulic oil if necessary.
3. Check that fluid level in the battery is correct (See
Section 4.3, Battery Maintenance).
4. Check the engine oil level and fuel level.
5. Check that all guardrails are in place, the slide out
deck extension is secured with the pin and all
fasteners are properly tightened.
6. Check tire pressure; 50 psi (3.4 bar).
7. Carefully inspect the entire work platform for
damage such as cracked welds or structural mem-
bers, loose or missing parts, oil leaks, damaged
cables or hoses, loose connections and tire damage.
8. Move machine, if necessary, to unobstructed area
to allow for full elevation.
9. Place chassis and platform emergency stop switches
in the ON position (Figure 3-1) by pulling the
buttons out.
10. Verify platform/chassis switch is on
PLATFORM
(Figure 3-1)
.
11. Dual Fuel Models: set dual fuel selector to desired
position. Set to the center position to purge the system
when switching fuels. If the machine is to be operated
on propane, open the supply valve on the tank.
Note: When using LP gas, use clean, water free liquid
petroleum gas, preferably from a bulk storage tank.
Follow the instructions located on the power module
tray for filling the tank.
If you smell propane, close the supply
valve on the tank immediately until you
have located and corrected the leak.
12. While the engine is cool check the engine coolant
level.
DO NOT check coolant when engine or
radiator is hot, hot coolant can cause
severe burns.
SYSTEM FUNCTION INSPECTION
STAND CLEAR of the work platform while
performing the following checks.
Before operating the work platform survey
the work area for surface hazards such as
holes, drop-offs, bumps and debris.
Check in ALL directions, including above
the work platform, for obstructions and
electrical conductors.
Protect control console cable from possible
damage while performing checks.
1. Unhook controller from front guardrail. Firmly grasp
controller hanger in such a manner that the interlock
lever can be depressed, while performing the follow-
ing checks from the ground.
2. Turn controller key switch clockwise to ON.
Turn fully clockwise to start engine, releasing the
key once the engine starts.
Note: If the engine is cold, on gasoline / propane
models, hold the choke button in while starting the
engine. On diesel models, depress the glow plug
button and hold for 6 seconds to engage the glow
plugs.
3. Position drive/lift switch to DRIVE position.
4. With the speed range switch first in HIGH
TORQUE and then in HIGH SPEED depress the
interlock lever and slowly push the control lever to
FORWARD then REVERSE positions to check for
speed and directional control. The farther you push
or pull the control lever the faster the machine will
travel.
5. Push steering switch RIGHT then LEFT to check for
steering control.
6. Depress the interlock switch on the control handle
and position each outrigger switch to the EXTEND
position to deploy all four outriggers. Check the
drive enable indicator light, it should be off.
7. Fully retract all outriggers and check the drive
enable indicator, it should be on.
8. Rehook controller on front guardrail.
9. Turn the platform/chassis switch to
CHASSIS.
10. Push the throttle button in. Push chassis raise button
to elevate platform while pushing the tilt sensor (Figure
1) off of level. The platform should only partially
elevate and the tilt alarm should sound. If the platform
continues to elevate and/or there is no alarm STOP
and remove the machine from service until it is
repaired.
