Air Filter/Regulator
Foot Valve:
The Foot Valve, P/N B3P71 actuates the saw heads downward. Once the foot valve is depressed, it must be
held down. The stroke or downward movement of the saw heads can be reversed at any time by releasing on
the foot pedal. Since the Foot Valve rests on the floor, it is important to clean it regularly, as debris from
cutting can make its way into the valve, causing improper function. Do not maintain pressure on the Foot
Pedal, as the saw cannot reverse stroke.
Speed Control of Blades Movement:
The downstroke speed of the blades is controlled by the lower Speed Control Valve, P/N B3P60, No. 15. The
upstroke speed is controlled by the upper Speed Control Valve, P/N B3P60, No. 16. Both are located on the
right side of the floor stand and are connected to the main control 4-Way Valve. (See Diagram “D”) An easy
way to remember is the
upstroke
is controlled by the
upper
valve, and the
downstroke
is controlled by the
lower
(down) valve. Up is up, and down is down.
Length of Stroke Adjustment:
The D45AX is unique in that the travel of the air cylinder can be adjusted to stroke only the length needed
to cut a particular moulding.
Example
: The highest moulding to be cut is 2” high. To adjust the stroke:
1. Shut off air supply and disconnect power.
2. Manually lower saw blades so that they are 1/2” above the work.
3. Adjust Upstop Clamp, No. 5 to contact Accessory Valve, No. 3 (see Diagram “D” on Page No. 8).
A. Loosen Upstop Clamp by using a 5/16 hex wrench on socket cap screw.
B. Move Upstop Block upward on cylinder shaft to contact Accessory Valve, closing the valve.
C. Tighten socket cap screw at this position.
4. The blades will now return to this height.
Adjust the Downstroke Bumper, No. 17 to contact Arm Casting, No. 13 as soon as the blades have cut
through the work.
You now have eliminated wasted motion and time, thereby increasing production. Always provide a safe dis-
tance between the blade and the work. Re-adjust the blade guard whenever the clamp is changed to make sure
the blades are completely covered.
