1. INTRODUCTION
1.1 HOWARD WRIGHT LIMITED
Established in the 1950’s, Howard Wright Limited has built a reputation based on quality product and design
innovation. Today Howard Wright Limited equipment is found in healthcare institutions worldwide.
1.2 INTENDED USE
The M9 Stretchers are mainly used in assisting the diagnosis, monitoring, prevention, treatment and alleviation of
disease, or compensation for an injury or disability.
The M9 Stretchers are designed to be used by trained health professionals and, to a limited extent, members of
the public.
The M9 Stretchers are used generally within a hospital emergency department, day surgery clinic, X-Ray (M9 Trauma)
or throughout the hospital as a means of treatment for patients, resting and observation of patients and transporting
patients from one department or area to another.
The M9 Stretchers are intended to support adult patients aged 12 years and over with a minimum weight of 15kg.
The M9 Stretchers may accommodate one patient up to a weight not exceeding 250kg (including mass of mattress
and accessories).
1.3 TECHNICAL SUMMARY
1.3.1 VERSIONS
Two versions of the M9 Transfer stretcher are available.
• M9 Transfer (4-section patient platform)
• M9 Transfer (2-section patient platform)
This stretcher is supplied with electric operation only.
Various options and accessories are available for the M9 Transfer stretcher. Please contact Howard Wright Limited
for more information.
1.3.2 CONSTRUCTION
Howard Wright Limited products are manufactured from high quality durable engineering materials including steel,
aluminium and stainless steel with a durable epoxy/polyester hybrid powder coated finish. High quality durable
engineering plastics including Nylon, ABS, TPR & Polypropylene are also used.
M9 stretchers have a LINAK control box. This uses mains power at 220-240 V AC (50-60 Hz) to operate LINAK
actuators at 24 V DC. An on-board sealed lead-acid battery provides power when mains power is not available (e.g.
when moving the stretcher). Control buttons are located on a remote handset for adjustment of the backrest, deck
height, deck tilt, legraise and an auto-contouring preset function.

Technical Service Manual M9 Transfer Stretcher (M999-29, Version 11, June 2021) 13
6. MAINTENANCE & SERVICING
b) Electric controls
• Check that all of the buttons on the handset work correctly.
• Check that the lock out feature is functional on all handset button functions.
c) Electrical system
• Unplug the stretcher from the mains supply. Check all electric cables for cracks, cuts or damage from
crushing.
• Unplug the stretcher from the mains supply. Check that the potential equalisation terminal (POAG terminal)
is functional by measuring the resistance between the earth pin on the 3 pin plug and the potential
equalisation terminal. Check the resistance between the earth pin on the 3 pin plug and any other earth
cable on the stretcher (green and yellow cable). The resistance in all instances must be less than 0.20.
• Unplug the stretcher from the mains supply. Press any control button to check that the battery will power the
stretcher adjustments. It may be necessary to plug the power cord into the mains supply for up to one hour
prior to this test to ensure the battery is charged.
• Adjust the backrest, legraise, deck height and deck tilt. Check that there are no abnormal noises during each
functions full range of movement.
d) Backrest quick-release mechanism
• Adjust the backrest fully up. Move the CPR knob to the emergency position. Check that the backrest lowers
when force is applied to it. Check that the CPR knob automatically returns to the normal position when it is
released.
e) Bed ends
• Check that the bed end can be removed and reinstalled. If jamming occurs clean the bed end sockets and
bed end pegs and add a small amount of Vaseline (petroleum jelly) or food grade grease to the sockets.
f) Fold Down Handles
• Check that both handles lock in the upright position.
• Check that both handles fold down fully into recess and can be freely lifted again.
g) Castors
• Set the castor pedal in the brake position. Check that all four castors cannot swivel or roll.
• Set the castor pedal in the neutral position. Check that all four castors are free to swivel and roll.
• Set the castor pedal in the steer position. Check that the steer castor locks in line with the length of the
stretcher and cannot swivel. Check that the remaining castors can swivel.
h) 5th Wheel
• Check engagement of 5th wheel when in locked position.
• Check that the gas strut is energised and has no oil leaks.
i) Mechanical items
• Check that all bolts, screws, nuts and pivot-pins are securely fastened.
• Check both siderails. Raise siderail and check gas strut assists raising. Check siderail does not lower
unassisted. Check that the siderail latch automatically latches with the siderail in the raised position – this can
be seen visually and heard audibly. Lift the siderail latch and lower the siderail to see that it is in good working
order.
• Check that the power cord storage hook is not twisted or damaged.

14 Technical Service Manual M9 Transfer Stretcher (M999-29, Version 11, June 2021)
j) Accessories
• Check the siderail covers for rips, cracks or other damage.
