MAINTENANCE
1. Inspect hoses and connections daily. Replace damaged
components immediately with Williams Replacement
Parts only.
2. Tighten connections as needed. Use pipe thread sealing
compound when servicing connections.
3. Always use clean, approved hydraulic fluid and change
as recommended or sooner if the fluid becomes
contaminated (never exceed 400 hours). Follow pump
manufacturers instructions for changing and adding
hydraulic fluid. Use only good quality hydraulic fluid. We
recommend 8H1G or equivalent.
Never
use brake fluid,
transmission fluid, turbine oil, motor oil, alcohol, glycerin
etc. Use of other than good quality hydraulic oil will void
warranty and damage the cylinder, pump, hose etc.
4. Use an approved, high-grade pipe thread sealant to seal
all hydraulic connections. Teflon tape can be used if only
one layer of tape is used and it is applied carefully (two
threads back) to prevent the tape from being introduced
into hydraulic system. A piece of tape could travel through
the system and obstruct the flow of fluid and adversely
affect function.
Lubrication & Cleaning
Keep cylinder clean at all times.
1. Any exposed threads (male or female) must be cleaned
and lubricated regularly, and protected from damage.
Lubricate with light machine oil.
2. If a cylinder or ram has been exposed to rain, snow,
sand, airborne abrasive, or any corrosive environment, it
must be cleaned, lubricated, and protected immediately
after exposure. Daily clean exposed ram with clean cloth
dampened with light machine oil. Protect exposed ram
from the elements at all times.
3. Keep the hydraulic system as free of dirt as possible.
When not in use, couplers must be sealed with dust
covers. All hose connections must be free of dirt and
grime. Any equipment attached to the cylinder must be
kept clean.

Storage
Cylinders should be stored with ram plunger fully retracted
in a dry, protected area, not exposed to corrosive vapor, dust
or other harmful elements. When a cylinder has not been
used for a period of 4 months, it should be connected to a
pump and fully extended and then retracted a minimum of
5 times. This cycle will lubricate the cylinder wall, reducing
the possibility of corrosion and damage thereof.
How to remove faulty coupler:
If cylinder does not retract, secure load by other means.
Depressurize pump and hose, then remove the cylinder from
application. Disconnect and replace with new coupler.
Important:
Do not attempt to grasp 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
cylinder as shown in figure 2 below.
2. Operate pump to fully extend and retract the cylinder 2
or 3 times. The objective is to force the air bubbles up
hill and back to the pump reservoir.
3. Follow pump instruction manual to bleed the air from
pump reservoir. On most pumps, air can escape by
opening the oil filler plug/screw.
