TL33 Work Platform 3-5
3.3 Pre-Operation Inspection
NOTE: 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. Oil should reach the level of 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. (See 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. Check that the ground is capable of supporting the
outrigger loads, and is generally level. Apply
handbrake.
9. Taking each outrigger in turn, pull the locking pin
release lever out while simultaneously lowering the
outrigger leg. Ensure the locking pin snaps into
position in the lower slot.
(See Figure 3-3)
10. Lower all screw jacks until the load is just removed
from the road wheels. Level the machine as necessary
using the bubble level on the chassis to check in both
longitudinal and lateral directions. Retract the jockey
wheel until it is clear of the ground.
11. Turn both Chassis and Platform Emergency Stop
switches ON (rotate clockwise).
12. Turn key switch on Ground Control box to the
CHASSIS position (right-hand position).
13. Using the chassis control switches, fully elevate
booms no 1 and 2.
14. 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.
15. Check rotation left and right function.
16. Lower each boom until platform is returned to its rest.
17. Replace module covers.
18. Retract screw jack on one outrigger and check that
warning alarm sounds.
19. Return chassis key switch to OFF (centre) position.
20. Lower jockey wheel until it is in contact with ground.
Raise remaining screw jacks then return each
outrigger leg in turn to vertical position, checking that
locking pin snaps securely into upper slot on the
quadrant.
21. Check tyre pressures and thread depth.
