Daily Visual Inspection
Bishamon recommends that every UniLift be visually inspected daily before use. Detailed below is a suggested daily inspection checklist for normal
operating conditions and environments. Extreme or unusual operating conditions may require a more extensive inspection and maintenance
program. If you have any questions regarding the inspection or maintenance of any UniLift, do not hesitate to contact your local Bishamon dealer
or Bishamon Industries Corp. If any of the following conditions exist, REMOVE the UniLift from service and contact a qualifi ed service person.
Inspect the following items with the forks lowered.
1.
Visually check the general condition of the UniLift. Inspect for loose, worn, damaged or broken components.
2.
Visually inspect the frame, mast, outriggers and fork carriage for broken or cracked welds.
3.
Check the condition of the warning labels. The warning labels are for the safety of the operator. If the labels are worn, missing or
unreadable, REPLACE them before placing the UniLift back in service.
Inspect the following items with the forks fully raised.
1.
Visually inspect the wheels and rollers (6 total) for fl at spots, wear or damage.
2.
Visually inspect the cylinder area for hydraulic fl uid leakage.
3.
As shown in Figure 28, manually operate both linkage lever arms and check for smooth movement and complete load wheel retraction. To
check their operation, fi rst ensure the forks are fully raised and the key switch is turned to OFF. Carefully gasp each lever arm and rotate it
rearward until it stops. Release each arm and watch for smooth movement and complete load wheel retraction. There should be a defi nite
audible knock when the load wheel fully retracts and strikes the travel stop in the fork. If the load wheels fail to retract completely or any
binding is present, the lift MUST be repaired before continued use use or damage to the battery cover may result.
4.
Grasp the mast cover on each side and slide the cover off the roll pins. Next guide the cover upward allowing the cover to retract. Similar
to a window shade, the mast cover will retract completely. When released, the roller may spin for several turns releasing the spring
tension.
5.
When reinstalling the mast cover it will be necessary to re-tension the roller spring. To do so, turn the key switch to the ON position and
raise the forks to their maximum height. Take care not to put your hands or feet under the forks. Next, pull the cover downward and
reposition the holes over the pins on the fork carriage. Replace the clamp plate and screw. As demonstrated in Figure 27, lift the axle with
the fl at end out of the slot. Using a pair of needle-nose pliers, rotate the axle clockwise fi ve (5) full turns and place it back into the slot.
6.
Finally, reposition the mast cap on top of the mast and reinstall the two screws. Raise and lower the forks several times to ensure the mast
cover functions correctly. If not, check the spring tension (step 5) and ensure the yellow mast cover is properly aligned with the roller.
