How To Adjust The Brake/Steer System
Wear from continuous use may cause the trolley brake or steer action to not lock in properly over time.
This may need to be corrected by adjusting the length of the Brake Linkage Rod.
1. Lock the right hand brake/steer pedal (from the foot end of the trolley) into the brake position.
Check that the head end pedal on the same side is locking fully into the brake position at the same
time. If not, the Brake Linkage Rod may need to be shortened or lengthened accordingly, to
equalise the operation.
2. To adjust the Brake Linkage Rod, lift or remove the plastic base cover as per instructions above.
3. Loosen the rod end lock nut.
4. Remove the rod end retaining bolt and nut and then wind the rod end a half turn in (clockwise) to
shorten or out to lengthen the Brake Linkage Rod.
5. Assemble the rod end retaining bolt loosely and test the brake/steer action. Continue to adjust the
rod end until the system operates correctly.
6. Re-assemble, locking all bolts and nuts tight.
How To Replace a Castor
1. Check the replacement castor is the correct type (ie. brake or brake/steer, Catis or Tente brand).
2. Remove or lift up the plastic base cover as per the instructions above.
3. Set the brake pedal the neutral position. Loosen the pedal lock screws at castor to be removed.
Using a suitable marker pen, mark the position of the hex lug on the hex rod. Loosen the lock
screw on the hex lug to allow the hex rod to slide through. Use a pin punch on the end of the hex
rod, to drive clear of the castor.
4. Release the lock tab and remove the castor retaining bolts. Remove old castor. Remove any plastic
bolt-hole plugs if in the castor spigot and insert the replacement castor. DO NOT ROTATE THE
CASTOR SPIGGOT, AS THIS MAY ALTER THE CASTOR SETTINGS.
5. Align the hex rod with the hole in the castor spigot. If the hex rod will not slide through the spigot,
remove and rotate entire castor 180° and re-ft. Tap the hex lug back into the original position
using a soft hammer and tighten lock screw using medium strength thread locker. Replace the
castor retaining bolts together with the existing or new lock tab. Tighten the castor lock screws.
Bend bolt locking tabs into position against bolt heads.
6. Replace brake pedal ensuring adequate clearance both sides of the base for the cover.
