BEFORE USE
1. Before using this product, read the owner's manual completely and familiarize yourself thoroughly with the product, its components
and recognize the hazards associated with its use.
2. Verify that the product and the application are compatible. If in doubt, call Williams Technical Service 1-866-460-7995.
3. Inspect before each use. Do not use if broken, leaking or damaged components are noted.
4.
Replace worn or damaged parts with Williams authorized replacement parts only.
5. Use adequate eye protection when operating or near this device.
6. Ensure method of confirming load is accurate and working properly. Have gauge or load cell accuracy verified by qualified
personnel on a yearly basis.
SET UP
1. Connect and secure hoses, cylinders, fittings, gauges and pump etc. noting that the proper ports are connected. Always
secure threaded port connections with non-hardening pipe thread compound. Take care not to introduce compound into port
orifices.
If you are not trained and familiar with installing a valve, please have an authorized Williams service center
to perform this procedure.
Use an approved, high-grade pipe sealant to seal all hydraulic connections. When using teflon tape,
never apply the tape over ends of fittings where it can be torn loose and get into the hydraulic system.
TROUBLESHOOTING
1. System will not build pressure.
a. Check pressure setting of pump, see pump's service instruction.
b. Check and tighten all hydraulic connections.
c. If trouble is not corrected, remove cylinder and hoses from the valve, place a gauge directly in valve port A and turn valve
to advance position. If no pressure developed, the unit should be taken to service center. If pressure develops, the cylinder
or connections are the problem.
2. Cylinder will not hold load. This is an indication of worn or damaged seals. Unit must be replaced/repaired by service center.
MAINTENANCE
1. Inspect hoses and connections daily. Replace damaged components immediately with Williams 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 Williams 8H1G or equivalent when using with hand pump, air pump, or electric pump. 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.
Storage
Depressurize pump, disconnect all hydraulic lines to prevent accidental operation. Wipe the unit clean. Store in a clean, dry
environment.
