Carriage Lock Lever
On the S350, S500 & S800, Slide the carriage lock lever to the left to lock
the carriage in place. Slide the lever to the right to release the carriage.
On the AS200, the carriage lock is a thumb screw on the right side of
the carriage. Tighten to lock, loosen to release.
CAUTION: Hold the crank lever or motor head whenever releasing
the carriage lock. It could slam down causing possible injury or
damage to the bit or machine.
REDUCTION GEARING
200mm Model Carriage Lock
On the S500 and S800 stands, there are two crank spindles:
Standard Ratio
One spindle is for for standard cranking and one for reduced gear ratio
cranking.
The reduced gear ratio allows the operator to drill with greatly reduced
effort when using large diameter core bits.
To switch from standard to reduced gear ratio cranking, simply remove
the crank handle from the main spindle and connect to the forward
Reduced Ratio
spindle on the left side.
Adjustable Roller Axle Bolts
ADJUSTING THE DRILLING STAND GUIDANCE
Loose guidance will cause the bit to run out-of-true and result in poor
performance, sticking and possible damage to the bit. If the rollers can
be turned by hand with the carriage locked, they are too loose.
To adjust the guidance, the two guide rollers on the left side are on
eccentric shafts. Turn the eccentric roller axle bolt until the clearance
is taken up on each roller in turn. Turn just enough so that the roller
cannot be turned by hand. Now test the tightness of the carriage by
