3.3 Pre-Operation Inspection
Carefully read, understand and follow all
safety rules and operating instructions.
Perform the following steps each day before
use. DO NOT perform service on Work
Platform with the platform elevated unless the
elevating assembly is properly supported.
1. Remove module covers and inspect for
damage, oil leaks or missing parts.
2. Check the level of the hydraulic oil with the
platform fully lowered and the Telescopic Boom
fully retracted. Oil should be visible on the filler
cap dip stick. If necessary top-up using ISO
No. 46 hydraulic oil.
3. Check that the electrolyte level in the batteries
is correct. (Battery Maintenance, Section 4.3)
4. Verify batteries are charged.
5. Check that the A.C. extension cord has been
disconnected from charger.
6. Carefully inspect the entire machine for
damage such as cracked welds or structural
members, loose or missing parts, oil leaks,
damaged cables or hoses, loose connections
and tyre damage.
7. Move machine, if necessary, to unobstructed
area where machine can be fully elevated.
8. Visually inspect the cylinders, hoses and cables
for damage. Check for missing or loose parts.
SYSTEM FUNCTION INSPECTION
9. Turn both Chassis and Platform Emergency
Stop switches ON (rotate clockwise).
10. Turn Keyswitch on the Upper Control box to
the ‘LOWER CONTROL SELECTION’.
11. Using the chassis control switches, fully
ELEVATE Booms no. 1 & 2 and EXTEND the
Telescope.
12. SLEW the Elevating Assembly through 180
degrees in both directions.
13. Visually inspect the elevating assembly and
cage mounting/structure, lift cylinders, cables
and hoses for leaks, damage or erratic
operation. Check for missing or loose parts
such as nuts, bolts and circlips.
14. Test that the Emergency Lowering Valves on
each of the Lift Cylinders is operating correctly
as detailed in Section 3.4. PUSH the
Emergency Stop Button to identify that
functions will indeed cease when depressed.
15. Operate the manual telescopic retraction
system using the Handpump to test that it will
work. (Not required on ANSI machines).
16. LOWER each boom until the Elevating
Assembly is fully stowed. Climb into the
Platform and check that the Platform is level. If
not adjust as shown in the Platform Levelling
Section of this manual. Repeat all the above
tests from the Platform Controls. Push the
Emergency Stop Button to identify that
functions will indeed cease when depressed.
Bring the machine back to the stowed position
and retract the Telescopic Cylinder.
18. PRESS the Service Horn to see that it is
operational. Select the DRIVE function. While
pressing the Joystick Interlock Switch slowly
PUSH the Joystick to DRIVE FORWARD, and
then PULL to DRIVE REVERSE, to check for
speed and proportional control. The farther you
push or pull the Joystick the faster the machine
will travel.
19. PUSH the Steering Switch RIGHT and then
LEFT to check for steering control.
20. RAISE the Elevating Assembly until the Boom
Rest Limit Switch is no longer activated and
then repeat the Drive Function test. Only low
speed (‘ CREEP SPEED’) should be available.
The System Function Inspection is then complete.
If there are any concerns about the safe use
or operation of the A38E following this
Pre-Operation Inspection DO NOT USE
THE A38E WORK PLATFORM. Contact your
supplier or Snorkel’s Product Support
