Pressure Relief Procedure
1. Close the supply pump’s bleed-type master air valve
(required for pneumatic systems).
2. Open the dispensing valve until pressure is fully
relieved.
3. Open the fluid valve at the pump fluid outlet. Leave
the drain valve open until you are ready to use the
system again.
If you suspect that the dispensing valve, extension, or
grease fitting coupler is clogged, or that pressure has
not been fully relieved after you have followed the steps
above, very slowly loosen the coupler or hose end cou-
pling to relieve the pressure gradually, then loosen it
completely. Then clear the clog.
Replacing the Service Hose
1. Relieve the pressure.
2. If the hose reel is enclosed, remove enclosures as
necessary to access hose reel (F
IG. 15).
3. Fully extend the hose (B) and latch the reel.
4. Attach a C-Clamp (A) to the reel flange to help pre-
vent the reel from unintentionally becoming
unlatched and spinning freely (F
IG. 16).
5. Remove hose stop from hose end and put all the
parts in a safe place to reinstall on the new hose
later (F
IG. 17).
a. Loosen and remove screws (aa) and nuts (bb).
Never allow the reel to spin freely. Doing so causes the
hose reel to spin out of control, which could cause serious
injury if you are hit by the hose or other moving parts.
