Adjusting the Operating Lever
Refer to F . 7 for the following instructions.
IG
The Accu-Shot valve operating lever (36) can be
adjusted using the adjustment set screw (41) and check
nut (40). The Accu-Shot is shipped with the lever
already locked and set and therefore does not normally
require adjustment. It may need adjusting after being
used for some time or when the valve is removed.
1. Relieve pressure, see Pressure Relief Procedure,
page 5.
2. Loosen the check nut (40).
3. Tighten or loosen the set screw (41) until the
required position is reached.
4. Fully lock the check nut (40) keeping the set screw
(41) in position.
NOTE: When the adjustment set screw is loosened, the
operating lever rest position (valve closed) moves away
from the grip. Once the adjustment has been performed
the position of the lever with respect to the grip must be
as illustrated in the overall Dimensions. See page 13.
