GRM SNIPER Operation & Instruction Manual

• The GRM "SNIPER" Grease Guns are heavy-duty, industrial grade and
precision-made. Use it where proper valve lubrication is a part of a
planned maintenance program.
• The equipment is inexpensive and many users dedicate a gun to
each type of valve lubricant used. The guns are made to pump "J" or
"K" size sticks of heavy-duty valve lubricants or injectable packings
where pressure of 10,000 psi is needed for proper lubrication.
• Utilization of industry-standard lubrication fittings will reduce
manpower needs and improve lubrication efficiency.
FOUR EASY STEPS TO LOADING THE GRM "SNIPER" HAND GUN
1.
- Unwrap the lubricant.
- Lubricants in "J" and "K" size sticks
are wrapped in easy to remove plastic.
- Lubricant sticks are soft and may need
to be broken apart as needed.
2.
- Insert the stick into the empty barrel.
- One stick fills a barrel.
TIPS ON PROPER VALVE LUBRICATION
There are five kinds of fittings that the On guns with a pressure gauge, pump lubricant
buttonhead coupler will attach to. When into the valve as long as the pressure rises and
fitted together, lubrication can be made the valve takes lubricant. When the valve is full,
while the valve is under pressure. the pressure will cause a drop reading on the
gauge. If no gauge is used, the lubricant begins

"SNIPER" Screw-Prime Hand Held
High Pressure Grease Gun (18" swivel hose)
• The GRM "SNIPER" is constructed of high-quality materials and
engineered for years of heavy-duty use. They are virtually
maintenance-free, and in-stock replacement parts are
immediately available to insure years of continuous service.
• This gun comes equipped with an 18" swivel hose assembly and
giant buttonhead coupler compatible with industry-standard
valve lubrication fittings.
• The GRM high pressure gauge and adapter accessory is
available to assist maintenance people in more efficient valve
service.
3.
- Replace screw handle then tighten
collar and turn handle until lubricant is
pressed into the head end of gun.
- If desired, purge old lubricant from
pump, hose and coupler by stroking
the pump handle until new grease is
visually observed being forced out of
the exit of the coupler.
4.
- Continue pumping by screwing in the
handle after several strokes of the
pump handle.
AMOUNT OF LUBRICANT LUBRICATION CYCLES
The amount of lubricant varies greatly
depending on how ofter the valve is
opened and closed. Less lubricant in the
seating area is lost when valves remain
open. Constant opening and closing may
require more frequent lubrication.

GRM HIGH PRESSURE GAUGE (OPTIONAL)
• A high pressure silicone oil filled gauge measuring 0 to 15,000 psi
• Case is stainless steel with male 1/4" connection
• Equipped with heavy-duty glass 2 1/2" dial
• Designed specifically for lubrication equipment
• When the lubricant pressure reaches the proper point, the gauge needle
will drop indicating the valve is fully serviced
• It can be used to indicate proper valve adjustment and other valve
function
