Air Supply:
The air supply must be turned off and all electrics disconnected before making adjustments on the power feed.
A working pressure of 75 PSI (pounds per square inch at 5.4 kg/cm
2
) is required. An industrial-type compressor
of at least 3 CFM (cubic feet per minute) is recommended. An additional 3 CFM is required for Spray Mists. A
conveniently located valve should be supplied by the user to shut off the air line. Arms should be raised or
lowered by hand when setting up machine. The machine must use clean, filtered air. The speed of descent of
the saw head will vary if the air pressure varies. An Air Filter/Regulator/Lubricator is essential.
FR:
An Air Filter/Regulator is installed ahead of the air inlet to the machine. This system helps prevent foreign material from
entering the system. It also provides lubrication in the air supply which helps prevent valves and cylinders from sticking.
The FR is comprised of two different components.
1. The Air Filter Bowl is located on the left side and is provided with an automatic drain. This collects and
then releases foreign matter and condensation collected by the air filter.
2. The Pressure Regulator , which is located on top of the air filter, controls the amount of air pressure
allowed into the system. An operating pressure of 75 PSI @ 5.4 kg/cm
2
is required. (This is set at the
factory.)

Trouble Shooting the Pneumatic System for Downfeed of Saw Head:
If the Air Feed no longer has smooth action, check the Downstroke Control Valve, P/N 2B3P61 or P/N B3P60. If
there is no speed control, replace with Part No. 2B3P61 or P/N B3P60. If air is leaking from the bottom of the
cylinder, replace Cylinder with P/N 2B3P05 (for DM200R); P/N B3P306 (for 16” DM400); or P/N B3P308 (for 20”
DM400).
4-Way Valve:
The 4-Way Valve is the main control, five port valve located on the Air Feed Unit. If the saw is sticking in the up or
down position, the spool located in the valve probably is not shifting from side to side as necessary. This condition
is caused by unclean air passing through the system. The internal parts become gummed up, and the air pressure can
no longer shift the spool. A broken spring in the valve is another common cause. A 4-Way Valve Repair Kit, P/N
B3P76 is available for the valve.
