AIR MOTOR:
Connect to an air supply with line pressure of approximately 90 p.s.i. A Martindale
Automatic Filter-Lubricator must be used to keep the motor adequately lubricated. Failure
to do so will void warranty. The angle head should be greased through the flush fitting on
the right side of the head after every 8 hours of operation. Attach grease tube to gun,
insert nozzle in fitting and pump 4 to 5 times while squeezing the tube. Grease the gear
case, which is located between the air motor body and the spindle housing, in same man-
ner after every 250 hours of operation.
SAWS & V-CUTTERS:
This special 18,000 RPM Kut-Kwik Undercutter is designed for use with 3/4” dia. and 7/8”
dia. x 5/16” hole Diamond Coated Cutting Wheels. These wheels are available in thick-
nesses, as shown in the Martindale Products Catalog or on line at
www.martindaleco.com.
Some customers have experienced success using tungsten-carbide saws with this
undercutter as the speed of this unit lends itself to the higher speeds required for carbide.
Because of the brittle nature of carbide these saws are susceptible to breakage and must
be used with extreme care so as not to wedge the saw in the slot.
OPERATION:
To attach the saw arbor rotate spindle by hand until holes line up in shaft and housing.
Insert lock pin through hole. Put diamond wheel on arbor making sure diamond wheel is
seated on shoulder. Screw the arbor into the head. DO NOT OVER TIGHTEN. Note:
Diamond Wheels will cut when rotated in either direction but if saws are being used care
must be taken to assure the saw teeth are pointed in a counter-clock-wise direction.
Tighten the retaining nut with the two 3/8” wrenches. Rotate the nylon depth gauge to
allow the desired depth of cut. With the cutter wheel to the operator’s left, start cutting at
the riser and pull the tool back toward the operator. Experience will show the operator the
proper cutting rate.
It is recommended that a Protective Mask and Eyeshield be worn when undercutting to
insure operator safety and comfort.
