MAINTENANCE
1. Inspect hoses and connections daily. Replace
damaged components immediately with Porto-Power
Automotive Replacement Parts only.
2. Tighten connections as needed. Use pipe thread
sealing compound when servicing connections.
3. Use only a good grade hydraulic oil. Avoid mixing
different types of uid and Never use brake uid,
turbine oil, transmission uid, motor oil or glycerin.
Improper uid can cause premature failure of the
ram and the potential for sudden and immediate loss
of load. We recommend Hein-Werner HW93291 or
equivalent.
Adding oil
1. With ram fully lowered, set pump unit in its normal,
level position. Locate and remove oil ller screw.
2. Fill until oil is within 3/8" of the oil ller screw hole
opening, re-install oil ller screw.
Changing oil
For best performance and increased system life, replace
the complete uid supply at least once per year.
1. With ram fully lowered, remove the oil ller screw
from the pump reservoir as above.
2. Lay the pump on its side and drain the uid into a
suitable container.
Note: Dispose of hydraulic uid in accordance with
local regulations.
3. Set pump in its level upright position.
4. Fill with good quality jack oil to within 3/8" of the oil
ller screw hole opening. Reinstall oil ller screw.
Lubrication
A coating of light lubricating oil to pivot points and
hinges will help to prevent rust and assure that pump
assemblies move freely.

Cleaning
Periodically check the pump piston and ram for signs
of rust or corrosion. Clean as needed and wipe with
an oily cloth.
Note: Never use sandpaper or abrasive material on
these surfaces!
Storage
When not in use, store with the pump piston and ram
fully retracted.
How to remove faulty coupler:
If ram does not retract,:
1. Secure load by other means.
2. Depressurize pump and hose
3. Remove the ram from application.
4. Disconnect and replace with new coupler.
Important: Do not attempt to grasp ram with pliers or
wrench without rst wrapping the jaws of such tool with
rags or similar padding.
How to bleed air from system:
1. Place pump at a higher elevation than the hose and
ram as shown in gure 3 below.
2. Operate pump to fully extend and retract the ram 2
or 3 times. The objective is to force the air bubbles
up hill and back to the pump reservoir.
3. To bleed the air from pump reservoir, simply open
the oil ller screw. Re-install after bleeding.
