Flow Restrictor Valve Replacement 
WARNING
 
Closely read and adhere to the following instructions whenever you remove and 
install the flow restrictor valve. Failure to properly install the flow restrictor 
valve can result in serious injury or death to personnel or damage to the 
equipment. 
The flow restrictor valve, Figure 4-7, is located inside the base of the hydraulic lift 
cylinder. If the flow restrictor valve needs to be removed or replaced, it is important that 
it be properly reinstalled. 
1.  Raise the platform and masts high enough to access the fitting. Support the 
raised platform using a forklift or hoist to prevent it from lowering. 
WARNING
 
Never work under the lift while it is raised unless the platform is fully supported 
to prevent it from lowering. Failure to properly support a raised platform can 
result in serious crushing injury or death. 
2.  Remove the hydraulic line from the fitting. Then, remove the fitting. 
3.  Remove the flow restrictor valve using a 3/16” allen wrench. 
4.  When reinstalling the flow restrictor valve, make sure it is tightened in all the 
way against the bottom. 
5.  When reinstalling the fitting, do not tighten it against the flow restrictor. If the 
fitting is turned in too far, it can reduce or stop the oil flow to the cylinder. 
6.  Finally, reconnect the hydraulic line to the fitting. Make sure the o-ring seal on 
the face of the fitting is not cut or tore.
