Air supply
Tools of this class operate on a wide range of air pressure. It is recommended, that air pressure to
these tools do not exceed 90 PSI / 6,3 bar at the tool while running. Higher pressure and unclean air
will shorten the tool-life because of faster wear and could create an unsafe condition. Water in the air
line will cause damage to the tool. Drain the air tank daily. Clan the air inlet filler screen on at least a
weekly schedule. The recommended hook-up procedure can be viewed in Figure 1. The air inlet (B)
Figure 2. used for connecting air supply has standard 1/4" NPT Thread. Line pressure or hose inside
diameter should be increased to compensate for unusually long air hoses (over 7,5m). Minimum hose
diameter should be 1/4" i.D. but 3/8" i.D. is recommended.
Operating
On tools with regulators the air regulator (A) Figure 2. can be used as an air throttle if there are no
other means of regulating air. Turn the air regulator (A) all the way in and adjust outward until desired
speed. Daily before using and before putting tool into operation, disconnect air hose and pour about
one teaspoonful of recommended oil (see lubrication and Maintenance) into tool air inlet. Blow out air
line to clear it of accumulated dirt and moisture, connect tool and operate on low throttle to allow oil to
be carried to the interior of tool. Let the tool do the work. Do not put extreme pressure on the
machine. This will only slow down the speed of the cutting wheel, reduce cutting efficiency and put
additional burden on the motor. Start the tool off the work. Set it down on the work evenly and move in
the direction desired to make the cut. When finished cutting, lift off the work before stopping the
motor.
