System Flushing Procedure
With platform fully down, drain hydraulic fluid from hydraulic reservoir into a clean, empty
container.
When the hydraulic reservoir is empty, remove suction strainer and hoses.
Remove the bypass filter and hose.
Flush the hoses with clean hydraulic fluid.
Discard old bypass filter element and replace.
Flush out the reservoir with hoses removed from the hydraulic reservoir.
Reinstall all hoses removed in the previous steps.
Fill hydraulic reservoir with filtered, fresh hydraulic fluid (refer to Lubrication Chart).
Loosen output hose fittings at pump to flood with hydraulic fluid. Tighten fittings.
Start up the machine. Briefly operate all functions. Two or three lift cycles may be necessary to
purge all air from lift cylinder(s).
When the above procedures have been completed, fill hydraulic reservoir to full mark on sight
gauge.
Check all leaks and correct as necessary. Machine is now ready to be placed back in operation.
Note:
Avoid mixing petroleum and synthetic base fluids. It is not advisable to mix fluids of different
brands or types, except as recommended.
