FREQUENTLY ASKED QUESTIONS cont’d:
Q: Can I paint the valve?
A: Painting valves is acceptable as long as the following precautions are taken:
1- All ports must be plugged
2- Spool must be masked or taped off completely.
Any paint on the spool will cause leakage when it chips off. Warranty is void if any valve is returned with paint on
the spool.
Q: What is the typical use of the “Hydraulic Kick-out”?
A: The typical set-up for using hydraulic kick-out is the retraction of a log splitter cylinder. In this case, the cylinder can
retract unmanned while another log is being loaded onto the splitter.
GENERAL INFORMATION:
Pipe Thread Sealant - Warranty is void when Teflon tape is used to seal pipe threads. This is because Teflon tape is a
friction reducing agent which allows customers to over-torque fittings. We recommend using a sealant that does not include
friction reducing agents i.e. Lead Plate.
