Groover Maintenance - Anvil GRUVLOK 1007 Manual

GROOVING MAINTENANCE
Due to the use of sealed bearings, the 1007 and 3007 Roll Groovers require very little maintenance.
A. GENERAL
1. Pull the bottom roll shaft out the front of the Groover.
2. A protective film of light oil should be applied to all rollers and
guide roll mounting plates. Frequency of application will vary due
to environmental conditions but shall be sufficient to prevent the
formation of surface rust.
B. REPLACEMENT PARTS
Please contact your local Gruvlok branch to purchase replacement parts
and accessories for the Roll Groover. To facilitate ordering, an exploded
drawing of each machine along with replacement parts listings are
presented in the next section.
C. HYDRAULIC MAINTENANCE
If you are having problems achieving or maintaining hydraulic pressure,
the following user serviceable items should be checked:
1
Verify that the release valve knob on the pump is not hitting the pump housing
prior to the valve closing completely. There should be a slight gap between the
stop located on the knob and the pump body. If there is not, loosen the two set
screws using a 1/8" allen wrench and reposition knob accordingly.
2
Check hydraulic fluid level. Fully retract hydraulic ram piston by turning
pump release valve counterclockwise. Remove filler cap from the rear of the
reservoir body. The fluid level should come to the bottom edge of the filler hole
when the pump is level and resting horizontally on its base. Mobil DTE 24
hydraulic oil or its ISO 32 equivalent should be used.

Bleeding air from the system is necessary.
Air can accumulate in the system through prolonged use as well as repeatedly
making-up the quick connect coupling to the hydraulic ram.
BLEEDING PROCUDURE IS AS FOLLOWS:
1. Disconnect quick connect coupling and remove hydraulic ram from
the top of the Roll Groover.
2. Reconnect hydraulic ram to pump and allow hose and ram to
hang down.
3. Close release valve on pump and pump to fully extend hydraulic
ram. Tilt pump to the right (hose side) to eliminate high point in
hose and open release valve allowing the hydraulic ram to return to
above its fully retracted position. Repeat the above procedure fully
extending and retracting the hydraulic ram several times, thereby
releasing the trapped air into the pump reservoir.
4. Recheck fluid level and add as required.
