apply a few drops of quality oil on the following surfaces
(See Figure 2):
• Along the breech bolt surface and where the sleeve con-
tacts the breech bolt.
• Along the breech bolt surfaces on the receiver where
the bolt contacts the receiver as it is worked.
Avoid applying too much oil. Only a light film is neces-
sary. Cleaning and Maintenance Suggestions should be
followed before each oiling.
O PERATION OF THE S AFETY
The safety can only be operated when the firing pin is
cocked. To cock the firing pin, lift up on the bolt handle
and then return it to the locked position. When the firing
pin is cocked, an indicator is visible at the rear of the bolt
(See Figure 3).
