ASSEMBLY

There should be no play, vertical or horizontal, in the
arm relative to the column, if you can move the arm
up, down or sideways when {he arm lock is unlocked,

use the following steps to tighten the arm.

Note:

The arm should pivot only when the arm lock

knob is unlocked and pulled forward to com
press the spring.

■ Using a Phillips screwdriver, remove the rear cover

screws (2) and rear cover from the back of the arm.
This uncovers the bolts on the column .

■ Tighten the top two bolts evenly until the arm is firm

and there is no vertical or horizontal movement.

■ Also check the two bottom hex nuts. It is not

necessary to tighten them as tight as the upper
bolts. However they should be tightened even and
snug.

■ Replace the rear cover and rear cover screws.

■ Tighten screws securely.

The purpose of this procedure is to check whether the
inner column tube is snug in the housing and to

remove any looseness. Looseness could result in a
poor cut or difficulty in elevating the carriage. The

column tube is the upper portion of the column and

extends from the column support.

Note:

It is criticalo remove all looseness with this

procedure. If this procedure is not done cor
rectly, following adjustments will be wrong and
could result in machine damage.

This procedure checks both the elevating action and
the rotating action. If a check does not show loose
ness, do not perform the adjustment.

■ If the arm is not at 0’ (straight forward), release the

arm lock knob, set the arm, and re-lock the arm
lock knob.

place your hand under the front of the radial arm.

Press upward on the radial arm. There should be
