SAFETY PRECAUTIONS
Failure to comply may cause injury or damage!
It is important that the Raz Rehab Shower Chair be properly assembled and
all adjustments be made carefully. For clarification of any section of this

CHAIR CLASSIFICATION BASED ON MAXIMUM USER WEIGHT
AP / SP / AT 300 lbs (136 kg)
SAFETY INSTRUCTIONS TO CONSIDER FOR RETAIL PURPOSES
Forward Stability
The front 5” casters on all models are equipped with dual locks. The step-on lever activates
both the roll lock and the swivel lock. It is essential that the front casters be in the forward
and outward position before engaging the locks for optimum forward and lateral
stability.
USERS MAY NOT lean forward as this may cause the chair to tip forward.
USERS MAY NOT wheel down a ramp (SP, SPHD models) without an attendant who can hold
onto the chair during the descent.
WHEEL LOCKS ARE NOT BRAKES! Never allow use of the wheel locks to slow down
the commode when descending inclines as this could cause the chair to tip in the
direction of travel.
Lateral Stability
USERS MAY NOT lean over the edge of a Raz Shower Chair as this could cause the chair to tip.
USERS MAY NOT attempt to pick up objects from the floor by leaning over and reaching – a
reacher or assistance from others should be employed.
USERS MAY NOT position the Shower Chair on a side slope as this could cause it to tip.

3
Rearward Stability
USERS MAY NOT wheel up an incline on Model SP without ensuring that the optional rear anti-
tippers are in place. The optional anti-tippers must be ordered with the Raz SP and properly
installed before wheeling on uneven surfaces.
Ramps and Other Inclines
Ramps and other surfaces that are not level must be tested with an attendant to ensure that
they don’t compromise stability.
Anti-Tippers (SP models only)
Anti-tippers are an option of the Raz SP Shower Chairs. These are recommended whenever
the chairs are to be used on uneven surfaces such as ramps or sloped floors.
IMPORTANT!
THE REARWARD STABILITY OF THE RAZ SP IS AFFECTED BY THE MOUNTING
LOCATION OF THE REAR WHEELS, THE PHYSICAL AND CLINICAL CHARACTERISTICS
OF THE USER AND THE ANGLE OF THE BACKREST. THE NEED FOR ANTI-TIPPERS
SHOULD HAVE BEEN DETERMINED AT THE TIME OF THE PRESCRIPTION OF THE RAZ
SP WITH CONSIDERATION OF THE USER’S ENVIRONMENT.
Transfers
The most dangerous part of using any shower chair is the transfer. Since every chair has
different stability characteristics, it is essential to carefully review and test the transfer
technique to ensure that the procedure is safe.
The wheel locks are designed to prevent the self-propelling wheels from rotating. The dual
locks on the casters are designed to prevent the caster wheels from rotating and the caster
forks from swivelling. These do not and CANNOT prevent the tires from sliding if the floor is
slippery. Transfers should never be attempted with the shower chair positioned on
slippery surfaces since the wheel locks can only prevent the wheels from rotating. It is
recommended that transfers be performed on clean, dry non-slippery surfaces.
Transferring onto a Raz AP Shower Chair – always lock all four casters in their
out-bound position (front casters positioned in the forward and out position / rear casters
positioned to the rearward and out position) for maximum chair stability.
Transferring onto a Raz SP Shower Chair – always lock both front casters in their
out-bound position (positioned in the forward and out position) and fully apply both wheel locks
so that they securely engage the rear wheels.
NEVER use the footplates to assist in transfers. This could cause the chair to tip forward.
The footrests should be swung to the side or removed entirely during transfers to provide
unobstructed access to the shower chair.

SET-UP INSTRUCTIONS
Backrest Set-Up – AP / SP Models
Tools needed: 7/16” wrench, and 5/32” hex key
1. Remove Shower Chair from shipping carton.
2. Place a coved spacer on the outside of both
vertical backrest frame tubes. Align spacer
with hole on bottom of frame.
3. Lift the backrest to an upright position in
order to trap the coved spacers between the
backrest mounting plates and the backrest
frame tubes.
TIP: For one-person assembly, place one coved spacer on
the backrest tube just below the pivot point of the backrest
frame, partially lift the backrest up to secure it in place and
then place the second coved spacer lower on the backrest
tube and then lift the backrest to an upright position.
4. Insert an included 2” bolt with a washer
through one of the intersecting holes on the
backrest plate, then push through the coved
spacer and frame.
Select the middle hole for a 90° backrest,
rear hole for 85° or front hole for 95° backrest
angle.
TIP: A Phillips screwdriver can be inserted through one
plate and frame to temporarily secure the backrest in an
upright position.
5. Fasten the other end of the screw with a
coved spacer, washer and locknut.
6. Tighten the assembly with hex key and
wrench.
7. Repeat steps 4 to 6 for other frame
tube.

Seat Installation & Removal
1. Ensure the spring clips in the front seat brackets are in the unlatched position. To
unlatch the spring clips, squeeze the each clip inward to unlatch the free end from the
front seat bracket.
2. Slide the rear of the seat over the rear cross tube as the front of the seat is lowered onto
the frame. Check to make sure the rear seat brackets hook below the cross tube.
3. Continue lowering the front of the seat until the front seat brackets nestle onto the front
seat support tubes.
4. Secure the seat in place by latching the spring clips. To latch the spring clips, squeeze
each clip inward while moving the free end towards the seat until the spring clip clicks
into the seat bracket across the front support tubes.
5. Reverse process to remove seat from frame.
Caster Installation – AP / SP Models
1. Remove casters from accessory box.
2. Insert the caster extension tube into the lower frame receiver tube to the desired
position.
3. Line up the through holes in the frame and in the caster extension tubes. It may be
necessary to rotate the caster extension tube in order to line up the holes.
TIP: Locking the caster first makes this easier.
4. Insert the snap pin through the frame tube and the caster extension tube. Ensure that
the pins are completely through the tube and that the grey plastic clip is snapped
securely around the outside of the frame tube.
5. Repeat steps 2 to 5 as required.
Factory Setting - Caster Extension Position for SP Model
22” Rear Wheel Lowest hole on caster extension tube
24” Rear Wheel Second Lowest hole on caster extension tube
IMPORTANT!
Telescopic caster extension tubes allow for an adjustment range of 3”. However, the
higher the chair is adjusted – THE MORE PRONE IT WILL BE TO TIPPING. CASTERS
MUST NEVER BE INSTALLED TO DIFFERENT HEIGHTS, AN UNLEVEL CHAIR IS
EXTREMELY DANGEROUS FOR ANY USER.
CASTERS SHOULD ALWAYS BE INSTALLED AT THE HEIGHTS RECOMMENDED BY
THE MANUFACTURER. FAILURE TO DO SO MAY RESULT IN CHANGE IN CENTRE OF
GRAVITY, WHICH COULD CAUSE INJURY OR PRODUCT DAMAGE.

with axle spacer resting against the outside wheel bearing.
5. Depress release button and insert quick-release axle into receiver on axle plate until the
wheel assembly rests against the receiver.
6. If the locking balls do not protrude past the receiver, turn the lock nut counter-clockwise
with wrench to increase grip length. If there the wheel is loose and there is too much
play in along the axle, turn the lock nut clockwise to reduce grip length.
7. Replace hubcap by turning it counter clockwise with wheel stationary.
8. Repeat steps 3 to 8 for other wheel.
IMPORTANT!
THE LOCKING BALLS ON THE END OF THE QUICK-RELEASE AXLE MUST BE FULLY
