The hydraulic oil may be of sufcient temperature to
cause burns. Wear safety gloves and safety glasses
when handling hot oil.
1. Install the outriggers and level the unit as normal (refer to the operators manual for operating
instructions). Operate the hydraulic system for 5-10 minutes to warm up the hydraulic oil.
2. Remove the cover from the power unit assembly.
3. Place the rated safe working load for the machine (as stated under specications in the operation
section) on the platform. Do not use personnel as safe working load for this procedure.
4. Install a pressure gauge on the gauge port.
5. Remove the cap from the system relief valve (refer to gure 3-4) and turn the adjustment screw
counterclockwise, 2 full turns.
6. Operate controls to elevate the machine. Note that the machine will not raise until the relief valve
is properly adjusted.
7. Turn the system relief valve clockwise (refer to gure 3-4) until the machine begins to rise.
8. Elevate the platform fully and verify that the pressure does not exceed 165 bar (2400 PSI) at any
time during the lift cycle.
9. Replace cap on the system relief valve and reassemble cover.
MAST ASSEMBLY/DISASSEMBLY
Using a suitable lifting device, lower the work platform into a horizontal position (refer to gure 3-5).
If possible, place the machine unto a sturdy work table using a forklift.
Never attempt to lower the lift into a horizontal position
without the use of a suitable lifting device; bodily injury
or damage to the machine may result.
NOTE: Mark all components as they are removed to ease with re-installation in the correct
location and sequence.
PLATFORM ASSEMBLY REMOVAL
1. Extend elevating assembly far enough to expose the eight screws attaching the cage support
assembly to stage 6 by opening the emergency lowering valve and pulling on the cage guardrail.
2. Remove cover from the front of the platform assembly.
