CASTOR WHEEL AND FORK
TO RE-ASSEMBLE
STEP 3
Locate fork stem nut on the threaded end of the stem and tighten with a 19mm spanner just
enough to allow the fork to swivel freely.
STEP 4
To check for correct tightness, preform the following test:
a) Tip chair backwards and rest the push handles on the floor (remove the battery boxes
first).
b) Raise castor wheel towards ceiling, then gently push downward to either side. The wheel
and fork should freely rotate down and hang straight towards the floor after a pendulum -
type swing.
NOTE:
IF THE WHEEL STOPS ANGLED TO ONE SIDE, LOOSEN THE FORK STEM NUT
SLIGHTLY. IF THE WHEEL CONTINUES TO SWING TO BOTH SIDES ( LIKE A
PENDULUM), TIGHTEN THE FORK STEM NUT SLIGHTLY. CHECK BEARINGS FOR
EXCESSIVE PLAY BY GENTLY ROCKING THE FORK ASSEMBLY.
