BLACKHAWK! PORTO-POWER B65115 - Manual (Page 6)

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 fluid and Never use brake fluid,
turbine oil, transmission fluid, motor oil or glycerin.
Improper fluid 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 filler screw.
2. Fill until oil is within 3/8" of the oil filler screw hole
opening, re-install oil filler screw.
Changing oil
For best performance and increased system life, replace
the complete fluid supply at least once per year.
1. With ram fully lowered, remove the oil filler screw
from the pump reservoir as above.
2. Lay the pump on its side and drain the fluid into a
suitable container.
Note: Dispose of hydraulic fluid 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
filler screw hole opening. Reinstall oil filler 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 first 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 figure 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 filler screw. Re-install after bleeding.
