Troubleshoot: If your RoughRider
™
Does
Not Roll Straight
If one wheel has more resistance than the others, your chair will turn to the side to which that
wheel is attached. This turning occurs because the wheel is rotating slower on that side, as if you
were braking or pulling on it. This resistance will also make you work harder when pushing
because you will have to compensate for this unevenness.
Check to see if the chair rolls in a straight line
. Find a flat area with as few bumps as possible.
Roll your RoughRider at a medium speed while trying to push equally on each wheel. Let go
without shifting your weight and see if your RoughRider drifts to one side. If it does, this is
usually the side that is affected by one of the problems below. After trying any of the solutions
below, check to see if your chair rolls in a straight line.
Observe
. Look at the chair on a flat surface and notice what doesn’t look straight. Look at the
caster barrels, caster wheels, rear wheels, and side frame.
Uneven Tire Pressure
A chair will turn toward the tire with the lower pressure.
Solution:
Equalize the pressure in the two tires either by pumping up the lower pressure tire or by
releasing some of the pressure in an over inflated tire.
Dirty or Damaged Bearings
A chair will turn toward the side of the chair where the bearing is sticking (like braking on one side).
Solution:
Check the bearings in the caster wheel and rear wheel. See Bearings section; Check and
clean or replace bearings as appropriate.
Stuck X-Brace
A chair will turn toward one side if the X-brace pivot does not move easily or is jammed so that one
caster wheel is suspended above the ground. You should be able to see if this is the problem if you
look at how your 4 wheels contact a flat surface when you are seated in the chair.
Solution:
•
Loosen X-brace center bolt. The center bolt should not be tight. There should be approximately
0.5 cm between the locknut and the square tube. With a person seated in the chair, you should
be able to hold one caster wheel down and lift the other 2 cm (3/4 in.) above the ground with
little effort.
•
Check to make sure that there is a good locknut (nylock or split nut) to keep the X-brace center
bolt from falling out. Another option for a locknut is to use two nuts to make a jam nut. Thread
the first nut onto the bolt. Thread the second nut onto the bolt and tighten it firmly against the
first nut to create a locked nut.
•
Lubricate and manipulate the X-brace to loosen the joint.
