5. Screw back the Grease gun Head onto the Barrel, making sure to tighten
only half-way, leaving 2-3 turns before the Head is fully tight
6. Disconnect the Plunger Rod from the End Cap
7. Force the Plunger Rod in & out a few times in order to compress the grease and force out trapped
air in the grease to come out from the loose connection between the Grease Gun Barrel and the Grease
Gun Head
8. Hand tighten the Grease gun Head fully onto the Barrel
9. Start operating the Grease Gun 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 & 8 to Prime* the Grease Gun
10. Once all air bubbles are removed, fully tighten the Grease Gun Head onto the
Barrel.
(Note that when the Grease Gun is in continuous use, pressing the Air Release
Valve* helps force out trapped air).
Now, connect Grease Gun extension and Coupler onto the Grease Gun Outlet
using a thread sealant such as Teflon, to make a seal-proof connection.
(DO NOT over tighten as this may fracture the Grease Gun Outlet)
11. Start operating the grease gun. Grease will begin to flow out from the coupler. Keep running it, till a
bubble free clear stream of grease flows out. If this does not happen, then there is still some trapped air
in the grease. Repeat steps 5, 6, 7 & 8 to Prime* the Grease Gun
*On Grease Gun models fitted with Air Release Valve
** PRIMING GREASE GUNS
A common occurrence with all grease equipment is trapped air pockets in grease. Trapped air causes zero
or reduced grease
discharge. Removing Air Pockets from Grease is referred to as Priming or Air Bleeding.
It is highly recommended to prime the Grease gun, before it's used for the first time. Also, anytime in opera-
tion, if grease stops
coming out, the most probable cause is trapped air in grease. Refer to steps 5-9 for Priming of Grease
Gun.
If the Grease Gun has been in regular use, Priming can be done without having to remove the Grease Gun
Extension & Coupler
from the Grease Gun Head.
