General Description
The RBG 18V Cordless Grease Gun is a fully battery-operated, automatic grease gun. The
gun is designed for manual lubrication of grease fittings. It includes a pressure release valve to
relieve pressure in excess of 10.000 PSI (690 Bar) in the case of a blocked bearing, fitting, or
lubrication line.
Appropriate Use
The Grease Gun is designed to pump and dispense grease using a 18 Volt battery pack. Do
not substitute with any other 18 Volt battery pack. Any other use than expressed explicitly in
these instructions will void the warranty and any claim to liability.
Grease Gun Use and Care
Do not continue holding trigger if the Grease Gun is locked. This could damage the motor by
over heating causing fire. When not in use, keep battery pack away from other metal objects,
such as paper clips, coins, keys, nails, screws, or other small metal objects that could make
contact with terminals and cause sparks or fire.
Service
Avoid risk of injury by servicing the Grease Gun only through qualified repair personnel. Use
only RBG replacement parts. Use of unauthorized parts may create risk of injury and will void
the warranty. For service, please take the unit to a qualified service center.
Use Safety Equipment
ALWAYS WEAR SAFETY GLASSES. Always use goggles or a face shield, but DO NOT
depend on everyday eyeglasses as impact-resistant lenses; they are NOT safety glasses.
Always wear eye protection that conforms to GS (Geprüfte Sicherheit) Safety Standard.
PROTECT YOUR HEARING. To avoid possible hearing damage, always wear ear plugs
when using your grease gun for long periods of time.
WARNING
The Grease Gun can generate up to 10.000 PSI (690 Bar). High pressure grease can cause
serious injury. Hold the hose by the spring guard. Avoid accidental starting; ensure switch in
not depressed when inserting battery pack. Do not bend hose so it kinks. Replace the hose

Guidelines for Using Extension Cords
PROPER EXTENSION CORD IS CRITICAL. It is vital to use only good conditioned extension
cords that are not damaged in any fashion. When using an extension cord, be sure to use one
that is hefty enough to carry/support the current your product will draw. Any cord that is not
sufficient enough or is undersized will cause overheating and possibly cause electrical shock.
The following table illustrates the correct size to be use depending on cord length as well as
nameplate ampere rating. If uncertain, always use the next heavier gauge;
The smaller the gauge number –the heavier the cord.
Grounding Instructions
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides the path of least resistance for electric
current and reduces the risk of electric shock.
Charger is equipped with an electric cord that has a
POLARIZED plug. The plug MUST be plugged into a
matching outlet that is properly installed and grounded in
accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by a
qualified electrician.
CAUTION: IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS
PROPERLY GROUNDED. IF YOUARE NOT SURE IF IT IS, HAVE A CERTIFIED
ELECTRICIAN CHECK THE RECEPTACLE.

Pressure Adjustable Switch
Pressure adjustable switch was a patent design for dual flow grease gun.
Action:
When the point gap of pressure adjustable switch locates at “L” (Low pressure) site, it’s
represent that the maximum output pressure of the grease gun is 350 Bar (5,000 PSI), and the
output flow is 250 g/min. Under low pressure, this model has high grease output. When the
point gap of pressure adjustable switch locates at “H” (High pressure) site, it’s represent that
the maximum output pressure of the grease gun is 690 Bar (10.000 PSI), and the output flow is
55g/min. Under high pressure, this model has low grease output. This outstanding model
becomes a multi-purpose machine. (Picture A)
Pressure Relief Valve
The pressure relief valve will function when the
pressure over standard setting and it will release
pressure to ensure the grease gun safely operated. IT
CAN NOT BEADJUSTED BY YOURSELF
OCCASSIONALLY, and should be adjusted by
professionals with the professional equipment.
