The Barrett 7H and 10H models are designed for a maximum user weight of 114 kilos (18 stone). The
frame has been reinforced and components such as push handles, crossbraces and locking link
assemblies, along with their associated fixtures, have been upgraded to suit. It is therefore essential
that the correct replacement parts are used. Components from previous specification Model 7 and 10
are not compatible and if used would compromise the safety of the wheelchair.

Re-assemble heel loop to footplate and tighten nuts to 10 lbs/ft (13 Nm). Insert footplate stem into
hanger tube and tighten clamp to 35 lbs/ft (47 Nm).
The footplate should remain in a vertical position when required. This is maintained by semi-eliptic
spring acting between footplate and pivot tube. This does not normally require maintenance.

Ensure pivot bolts are not over-tightened as this will lead to fracture of brazed tabs to handle. Lubricate
with light oil.
9.6 Brake Adjustment
The Brake Shoe position can be adjusted by loosening the lock nut and repositioning the shoe. The
nuts should be adjusted to allow an operating force at the Brake Knob to be between 10 lbf to 13 lbf
(22 to 58 N) with tyres inflated to correct pressure (50psi/340 Kilopascals).

11.3 Inspection
Check Cross Braces for bending and evidence of cracks around pivot holes.
Check each tab on the sideframes for evidence of bending, elongation or worn holes, and cracks in
brazing or tubing.
11.4 Cross Brace Assembly Removal
Remove the two 1/4 UNF set screws securing the Cross Brace Assembly to each sideframe.
11.5 Cross Brace and Locking Link Assembly Fitting
Fit two 1/4 UNF set screws to secure the Cross Brace Assembly to each sideframe. Tighten until the
Cross Brace is just securely held, then loosen the nut half a turn.
The Cross Brace Assembly must be free to move without binding, but show no signs of excessive free
play. Lubricate with light oil, eg 3 in 1. Overtightening of Cross Brace Assembly screws will prevent
pivotting action and will lead to fracture of tab to side frame.

a torque of 30 to 35 lbs/ft (40 to 47 Nm) to secure the wheel to the wheelchair.
13.6 Tyre Fitting
Fit a strong rim tape and check that the inside of the tyre and the rim well are clean. Put one side of
tyre onto rim, pass the valve of the tube through the rim and partially inflate the tube until round in
shape. Fit the remainder of the tube into the tyre.
Starting at the valve fit the other bead of the tyre into the rim working outwards with the thumbs
ensuring the tube is not pinched between the tyre and the rim.
Before inflating to the correct pressure, centre the tyre on the rim by lining up the bead line on the
tyre sidewalls with the edge of the rim. Spin the wheel and check that the tyre rides evenly. If not
then adjust the tyre again and recheck. When running centrally, inflate the tyre to the correct
pressure.

TIPPING LEVER
PRESS
WHEEL HUB
SPOKES OMITTED
FOR CLARITY
Ensure the brake is not applied. With one hand hold the frame of the wheelchair and with the other
hand hold the spokes surrounding the hub and fully depress the centre button pulling the wheel away
from the wheelchair axle bush and releasing the centre button.
14.5 Wheel Fitment
Lift the frame with one hand and the wheel in the other hand. Hold the spokes surrounding the hub
and fully depress the centre button. Insert the axle fully into the axle bush and release the centre
button. Ensure that the wheel is fully locked. Pull wheel outwards without depressing the centre
button. If located correctly, the wheel will not come off. If a new axle has been fitted, length adjustment
may be necessary.
14.6 Adjustment
Assemble the wheel and spindle to the wheelchair. Opposing ball bearings on the spindle must fully
protrude past the inner face of the wheel bush. If they do not, slacken the nyloc nut on the outer end
of the spindle until this is achieved. Adjust the nyloc nut until 1mm end float (maximum). Excessive
end float will cause the quick release spindle to bend. Lack of float may cause incorrect fitting of the
wheel to the wheelchair.
MAINTENANCE
It is essential that the quick release axle and bush are kept lightly lubricated at all times to ensure ease
of action and it is recommended that a graphite-based lubricant is used for this application.
