2. The information in this manual has been carefully checked and is believed to be entirely reliable and consistent with the product described.
However, no responsibility is assumed for inaccuracies, or for liability arising out of the application and use of the equipment described.
3. Should the equipment be used in a manner not specified, the protection provided by the equipment may be impaired and the warranty voided.
4. Always wear safety glasses when using a grease gun. Keep work area clean & remove excess grease from tools, hands & clothing after use.
Do not use grease gun hose for other applications or at pressure levels above rated pressures.
Caution:
Excess grease, if left on floors, tools or equipment can create surfaces that become slippery.
UNPACKING
1. Unpack all the components from the box.
When unpacking the Grease Gun, carefully inspect for any damage that may have occurred during transit or storage.
Check for tears, loose parts, missing parts or damaged parts.
2. Ensure all packaging material are disposed of as per your local council guide lines.
ASSEMBLY
The K8081 Smart Grease Gun requires the extension hose or extension pipe to be assembled prior to use.
Choose ether the rigid or flexible extension hose.
Connect the desired Extension hose and Coupler onto the Grease Gun Outlet of the Grease Gun Head using a thread sealant such as Teflon (not included), to make a seal-proof connection.
(
DO NOT
over tighten as this may fracture the Grease Gun Outlet which could result in an air leak).
OPERATION
Priming Grease Guns
A common occurrence with all grease guns is trapped air pockets within grease. Trapped air causes
No
or
reduced grease
discharge.
Removing Air Pockets from Grease is referred to as Priming or Bleeding.
It is highly recommended to prime your grease gun, before it is used, if grease stops coming out, the most probable cause is trapped air in grease.
If your grease gun is regularly used, Priming can be done without having to remove the Grease Gun Extension & Coupler from the Grease Gun Head.
1. Screw and fully tighten the Grease Gun Head onto the Barrel in a Clockwise direction.
2. Place the plunger handle on a flat surface while depressing the bleeder valve and the plunger release and push down firmly on the grease gun.
Some grease will appear before air is expelled.
3. Start operating the Handle till grease starts flowing out continuously. (Note that the first discharge of grease may have some air bubbles).
If grease is accompanied with air
bubbles, repeat steps 5, 6, 7 to Prime the Grease Gun.
Greasing A Grease Fitting / Nipple
The grease coupler provided at the end of the grease gun extension has a jaw type construction.
The coupler jaws will snap on to a grease fitting and maintain a tight fit. When connecting the coupler to the grease fitting, press the coupler straight onto the grease
fitting to form a snug fit (Fig 1). Start operating the grease gun with the coupler as square to the grease fitting as possible.
Once greasing is completed, slightly tilt the coupler, twist and pull back (fig 2). The tilt and twist action will allow easy removal of the coupler from the grease fitting.
Changing Output Mode
The grease gun has two modes
Pistol Grip (Fig 3)
Pistol Grip mode is used to lubricate large bearings not requiring high pressure, beyond 3,000 PSI. Also, high output is recommended if tool is used to refill small
reservoirs of the automatic lubrication systems.
If in Lever Action Mode:
1. Push and hold the handle release button all the way in.
2. While still holding the handle with one hand, push the handle up.
Release handle
Lever Action (Fig. 4)
Changing to lever action mode will allow a greater working pressure up to 6,000 PSI.
If in Pistol Grip mode:
1. Push and hold the handle release button all the way in.
2. While still holding the handle with one hand, pull the handle down.
TROUBLESHOOTING
Problem
Cause
Remedy
Grease gun pumps little to no grease
a. Air pockets in grease
b. Dense or Frozen Grease
c. Grease Gun Extension Blocked
d. Grease Gun Head Blocked
a. Prime Grease Gun (refer to steps 5-9 of grease gun loading)
b. Use a lower viscosity Grease / add some oil to grease to make it more
viscous / heat the Grease Gun Barrel to lower unfreeze the grease
c. Remove Extension Hose. If Grease gun pumps grease without the extension, then
the problem is with the extension, which should be cleaned / replaced
d. Dis-assemble the Grease Gun Head to check for any contaminants blocking the pas-
sage of grease Clean & Re-assemble the Grease Gun Head
Grease leaks from the connection between the Grease
Gun Head or the Extension hose or the Coupler
a. Loose Connection
a. Inspect and tighten the connection using Teflon or another form of Thread Sealant.
Grease leaks from the Coupler body joint or from in-be-
tween the Coupler Jaws & Grease Nipple
a. Damaged Grease Coupler
Replace the Coupler
