*If the saw blade cuts obliquely, check for worn bearings in the blade guide heads.
-When the back stopper ball bearing is worn
Remove the blade stopper bearing, remove the adjustment bolt,and change the back stopper ball bearing.
(For bolt F and R)
-When the blade stopper ball bearing are worn
Change all the blade stopper ball bearings.(For bolt F and R)
The bearing will come off by removing the U nuts under the bearings.
-Before correction for oblique cutting, always disconnect the power cord.
The machine may start suddenly, leading to injury.
-Immediately after cutting, fragment are hot. Do not touch them directly with hands.
Wait for a while or hold the pipe with a cloth. Otherwise you may get burned.
2)Correction Procedure for Oblique Cutting
*If oblique cutting still persists after bearing replacement, make corrections in the following procedure:
(1)Prepare a 4” galvanized pipe.(Other materials acceptable.)
(2)Cut it once in an ordinary state.(Mark the pipe end face to indicate which side is top or bottom.)
(3)After rotating the pipe a half turn, cut it once more to a length of about 5mm.(Mark the pipe end to indicate
which side is top or bottom and right or left.)
(4)Measure the top, bottom, right and left lengths of that butt end with a rule, vernier calipers or the like.
A difference between these lengths indicates a oblique cut. A oblique cut value is a half of this difference.
