Flexible drive shaft (Fig. 3-5)
Flexible drive shaft should be removed and lubricated
with a good quality lithium grease every 20 hours. To
remove the flexible shaft, first remove screw (1), loosen
bolt (2) and remove the gear case then pull the shaft out
of the drive shaft pipe. Clean the shaft off and apply a
generous coat of lithium grease to it and insert if back
into the drive shaft pipe, turn it until it drops into place
then install the gear case, and install & tighten screw (1)
and screw (2).
WARNING!
Wear protective gloves when handling or performing
maintenance on the blade.
Angle transmission (Fig. 3-5B)
Check angle transmission or angle gear for grease level about every 50 hours of operation by removing the grease filler plug
on the side of angle transmission.
If no grease can be seen on the flanks of the gears, fill the transmission with a quality lithium based multipurpose grease up
to ¾ full. Do not completely fill the transmission.
Use a sharp blade. A dull blade is more likely to snag and thrust. Replace the fastening nut if it is damaged and hard
to tighten.
When replacing blade, purchase one recommended by TANAKA, with a 25.4mm (one inch) mounting hole.
When installing a saw blade (2), always face the stamped side up. In the case of a 4 tooth blade (1), it can be used
on either side.
Use correct blade for the type of work.
When replacing a blade, use appropriate tools.
When cutting edges become dull, re-sharpen or file as shown in figure. Incorrect sharpening may cause excessive
vibration.
Discard blades that are bent, warped, cracked, broken or damaged in any way.
