Due to the use of sealed bearings, the 1007 and 3007 Roll Groovers require very little maintenance.
A. GENERAL
1. Periodically unplug and thoroughly clean your Roll 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
/
" 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.
SECTION VIII - GROOVER MAINTENANCE
3. 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 procedure is as follows:
• Disconnect quick connect coupling and remove hydraulic ram from
the top of the Roll Groover.
• Reconnect hydraulic ram to pump and allow hose and ram to hang down.
• 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.
• Recheck fluid level and add as required.
