without load.

orKing instructions
On failure of the compressed air release the valve
lever! To achieve an optimum result, move grin-
ding tool uniformly back and forth with light pres-

of the machine, as well as the life of the grinding tool.

reVentiVe mAintenAnce
Without a tool clamped in check no-load
speed periodically and after each mainte-
nance. Even if the machine still operates
perfectly, the motor should be removed, cleaned and the
four slides checked for wear by a specialist after approx.
300 to 400 operating hours. The lubricant in the gear
head (Isoflex NBU 15) should be replaced at the same
time (do not wash out!).
