Storage
WARNING
The 918-I Roll Groover must be kept in-
doors or well covered in rainy weather. Store the machine
in a locked area that is out of reach of children and people
unfamiliar with roll groovers. This machine can cause se-
rious injury in the hands of untrained users.
Maintenance Instructions
WARNING
Make sure the ON/OFF switch is in the OFF position
and machine unplugged before performing any
maintenance or making any adjustments.
Maintain the 918-I Roll Groover according to these
procedures to reduce the risk of injury.
Cleaning
Use a soft damp cloth to clean the roll groover.
Clean the drive roll knurls with a wire brush before use
and as necessary during operation. When grooving stain-
less steel pipe, thoroughly clean the entire roll set with a
stainless steel wire brush.
Lubrication
On a monthly basis (or more often if needed), lubricate
the groover with a lithium based general purpose grease.
Always lubricate the roll groover after roll set changes.
Figure 18 – Grease Fittings
• Lubricate the groover at grease fittings (See Figure 18).
Add grease until a small amount pushes out.
• Apply a light lubricating oil to pivot points and areas of
relative motion, such as the depth adjustment nut and
the stabilizer feedscrew. Wipe any excess lubricant
from exposed surfaces.

The roll groover gearbox is designed as sealed systems
and should not require any additional grease unless
significant leakage has occurred. In those cases, the tool
should be returned to a service center.
Hydraulic Fluid Level
Remove the reservoir filler cap (Figure 19). The oil level
should come to the fill line when the pump is resting on
its base and the ram is fully retracted. Use only ISO 15
hydraulic oil.
Once a year, or more often with heavy use or use in dusty
conditions, the hydraulic oil should be changed. To drain
oil, remove the reservoir filler cap and drain the oil in a
container. Properly dispose of the used hydraulic oil per
the Safety Data Sheet (SDS) and local requirements.
Hydraulic system may need air bled after changing fluid.
To bleed hydraulic system, position ram lower than pump
by tipping the machine on its side. Extend and return the
cylinder piston several times to permit air to return to the
pump reservoir.

Changing Roll Sets
When changing roll set, always make sure
NOTICE
drive roll and groove roll markings match. Mismatched
parts can make improper grooves and cause leaks.
Always change rolls as sets – do not mix rolls from dif-
ferent sets.
Properly support the rolls and shafts while replacing.
Changing Groove Roll:
1. Fully retract the groove roll.
2. Fully retract the stabilizer wheel.
3. Loosen groove roll set screw (Figure 20). Grasp
groove roll and remove upper shaft and groove roll
from groover (Figure 21).
