HOSS OWNERS MANUAL
Introduction
Congratulations on your choice of a power wheelchair! It is a
dependable vehicle built for power and performance. Its easy to operate controls
give you more of what you are looking for in a wheelchair.
But it is important that you understand what your power wheelchair is,
and what it is not. Our power wheelchairs (like all power wheelchairs) are de-
signed to provide safe, reliable transportation to older or moderately physically
disabled individuals who have difficulty in getting around. It will safely take you
everywhere the specifications indicate as long as you follow the simple safety guide-
lines shown on the next few pages.
The power wheelchair is not an all terrain vehicle that you can use out
in the fields to drag brush around or climb steep hills. It was not meant to go
hunting in, or transport you thru hazardous environments. It also was not designed
for the severely handicapped individual who should not be in a power wheelchair.
You must have good stability, motor control and above all else, good common sense
to use our wheelchair, or any other brand. If you feel that you cannot safely oper-
ate this vehicle at all times, you should not use this power wheelchair!
Important
Please read the entire manual carefully before attempting to drive
your new power wheelchair.
Remember to read all service recommendations outlined in this manual
to achieve trouble free, safe and enjoyable operation of your power wheelchair.
Failure to follow the recommended service procedures will damage your power wheel-
chair and such damage is not covered under warranty. Contact your dealer if you
have questions after reading this manual.
ConvaQuip Ind., Inc. specifically disclaims responsibility for any bodily inju-
ries or property damage which may occur during or because of improper use or
any use which does not comply with applicable Federal, State, or Local laws
and ordinances or methods recommended in this manual. If in doubt about
your ability to operate your power wheelchair, consult your doctor.

HOSS - Owner's Manual 3
NOTE: MODIFYING AND/OR TAMPERING IN ANY UNAUTHORIZED MANNER
WITH THE WHEELCHAIR WILL VOID THE WARRANTY AND MAY CAUSE THE
WHEELCHAIR TO MALFUNCTION, EXPOSING YOU TO PHYSICAL HARM.
ATTENTION: This manual contains specific information about your power wheelchair.
While some of the information is the same for all power wheelchairs, make sure that
you follow the specifications and directions that apply to your powerchair. If you are
unsure of the style powerchair you have, contact your dealer.
Your powerchair is a vehicle which provides independence and freedom to people with
limited mobility. Driver error can cause injury to the driver and to other people. Please
use common sense, courtesy, and obey the following guidelines for vehicle operation.
READ THIS ENTIRE MANUAL
BEFORE DRIVING THIS VEHICLE.
Safety Guidelines
Always turn the power switch to the OFF position when stopped or when getting off or on the
Hoss. This keeps you from accidentally hitting the throttle and causing an accident. For
persons with limited lower body strength, or persons who make slide transfers and may
forget to turn the power switch off, we recommend special caution.
DO NOT operate the unit if it behaves erratically, or shows abnormal response, heating,
smoking or arcing. Turn the system off at once and call your dealer for service.
Use extra caution when riding your power wheelchair off of the pavement or on rough,
uneven or soft surfaces tipping and injury may result. See maximum incline rating on
specification chart.
Do not exceed the incline specifications for your Hoss wheelchair or it will become unstable
and tipping will result. Persons with limited ability to protect themselves (like persons
paralyzed on one side) should use protective equipment such as bicycle headgear. The
specification chart in your manual will indicate the maximum incline for your particular
style wheelchair.

4 HOSS - Owner's Manual
Keep your feet on the footrests while riding the power wheelchair to avoid hitting
them on objects as you drive. Always wear shoes while operating your power
wheelchair.
Always wear your lap belt when riding your power wheelchair.
Secure the removable seat assembly before operating the power wheelchair to prevent
yourself from falling from the seat while moving.
Remember, The power wheelchair is built to carry a single person. Do not carry pas-
sengers under any circumstances or accidents and bodily injury will occur.
Ensure driving surface, ramp, platform lift or elevator is capable of supporting com-
bined weight of user and wheelchair.
Always go straight up or down curb cuts. You want the front wheels and the rear
wheels to climb up or go down together, not one at a time. Not doing this will
result in the power wheelchair violently swinging from side to side (as a car
would in a ditch) or the power wheelchair overturning. Also approach curb
access ramps the same way, straight on, not at an angle. NEVER attempt to go up
or down a regular height curb or tipping and personal injury will result!
Warning Driving the power wheelchair in busy streets, busy parking lots, or in crowded
shopping malls can be dangerous for you or other people as you may be struck by a
vehicle or you might strike a pedestrian. Use caution in congested areas at all times.
Lean forward a slight amount when traveling up an incline.
NEVER leave your power wheelchair exposed to the elements. This includes storage
outside or carrying the power wheelchair on an outside car-lift during peri-
ods of high moisture ( mist, rain, snow, etc.) or any other inclement weather
(dust or sand storms, etc.). Use only a damp rag to clean your power wheelchair
(never use solvents or abrasive cleaners). The use of excessive water, as from a
garden hose or bucket may cause damage to your power wheelchairs electronics.
Use caution when driving off even a small curb or raised surface. The act of dropping
off the edge subjects the power wheelchair to extreme forces that can damage the
frame and other components. This type of damage is not covered under warranty.
Disconnect the batteries before performing any maintenance or if you will not be riding
the power wheelchair for more than a few days. This avoids both the possibility of
injuries due to shock and helps lengthen the battery life. Make sure that the batteries
are secure when you are using the power wheelchair.

HOSS - Owner's Manual 5
Follow the directions of your doctor and/or pharmacist at all times. Do not drive the
power wheelchair while taking medications that affect your reflexes or judgment,
as your driving will be impaired and accidents may result. Do not drink alcohol
or use any other stimulants while operating this or any other vehicle.
The following are important things to help you drive the power wheelchair in
the safest possible manner. Please take note of each and every one.
WARNING DO NOT engage in the following activities with your power wheelchair
or serious personal injury may result.
DO NOT ride the power wheelchair with the brake disengaged at anytime.
DO NOT drive the power wheelchair diagonally across inclines, turn sharp on an in-
cline or make turns at or near full throttle at any time. Doing this will result in the power
wheelchair losing traction and control which can result in tipping and possibly serious
injuries.
DO NOT drive the power wheelchair with the seat assembly higher than necessary as
tipping and serious injury may result. The lower the seat, the better your stability.
DO NOT drive the power wheelchair with under-inflated tires as this increases the
possibility of tipping and injury. Your stability and efficiency (power and range) are
also greatly affected.
DO NOT remain seated on your power wheelchair while it is being loaded into a vehicle
using anything other than a special wheelchair lift, or personal injury may result.
DO NOT ride on soft, uneven surfaces as this can cause lose of traction and control
causing tipping and that may result in serious injury.
DO NOT stop on any incline to rest or dismount. Although the electric brake will stop
and hold you, it is best to stop in level, flat areas where there is no possibility of rolling,
or tipping the unit or having the occupant fall out.
DO NOT ride your power wheelchair without wearing your lap belt at all times or
serious injury may result. This is especially important on ramps or inclines.

ConvaQuip Ind., Inc. POWER WHEELCHAIR TIE DOWN INFORMATION
WARNING: Do not engage in the following activities with your power wheelchair
or serious injury may result.
Do not remain seated on your power wheelchair while it is being loaded into a
vehicle using anything other than a special wheelchair lift.
Riding on a platform lift is dangerous. Failure to check weight capacity, turn off
controller, have the required precise driving control capability or have the wheel-
chair properly maintained could result in serious injury or death.
Do not use the power wheelchair as a seat in a moving vehicle. As of this date, the
Department of Transportation has not approved any tie down system for transporta-
tion of a user while in a power wheelchair in a moving vehicle of any type. The rider
must be seated in a regular automotive seat and restrained by an approved automobile
safety belt. The rider must be warned that there is a many times greater likelihood of
sever injury or death in the event of an accident if they are not in the provided automo-
tive seat and restraint system. The following attachment points are provided for the
sole purpose of securing the mobility device without the rider. The power wheel-
chair and batteries MUST be independently and properly restrained or stored in a
separate compartment so as to prevent it from causing injury in an accident.
CONVENIENT TIE DOWN POINTS
The following is a list of convenient locations that the straps from a 4 point secure-
ment system could be anchored on a HOSS or HOSS Jr. These products have not
been crash tested and certified as crash worthy using these locations.
HOSS & HOSS Jr.
Back anchor points - Place a strap around the lower portion of each armrest support.
Front anchor points - Place a strap around each anti-tip wheel support arm just
above the small anti-tip wheel.

HOSS - Owner's Manual 7
DO NOT drive up, down or across inclines greater than the rating for your style power
wheelchair or tipping will result. Refer to the Specification Sheet (Please Note:
Soft surfaces reduce the incline capability by more than 50%). Wet or slick surfaces
reduce steering and braking controls tremendously. Use extreme caution in these
circumstances.
DO NOT travel down ramps at high speed. Doing so will reduce traction and increase
stopping distance.
DO NOT allow the power wheelchair controls to become wet. Never wash off the
power wheelchair using a hose or a stream of water, drive through standing water or
ride in the rain. Possible loss of control and/or electronic damage will occur. Do not
attempt to ride a power wheelchair that has been soaked until it has had a chance to dry
thoroughly.
DO NOT leave the power wheelchair where it is exposed to high temperatures
(a car trunk, etc.) or to poor weather conditions such as rain or snow or freezing
conditions as damage to the unit will occur.
DO NOT disassemble any wheel at any time while still inflated. The pressure may
blow wheel rims apart while you are loosening them.
DO NOT ride the unit near platforms, stairs, ledges, curbs or in any other potentially
dangerous situation as serious injury can result.
DO NOT ride the power wheelchair over power cords, oxygen lines, hoses or any other
material that could become entangled in the wheels or get caught in the drive mechanism
of the power wheelchair or while connected to equipment off of the power wheelchair.
DO NOT attempt to reach objects if you have to move forward in the seat.
DO NOT attempt to reach objects if you have to pick them up from the floor by reaching
down between your knees.
DO NOT lean over the top of the seat back to reach objects from behind as this may cause
the power wheelchair to tip over or cause you to fall out.
DO NOT shift your weight or sitting position toward the direction you are reaching as the
power wheelchair may tip over.
DO NOT tilt the power wheelchair without assistance.
DO NOT use an escalator to move a power wheelchair between floors. Serious bodily
injury may occur.

8 HOSS - Owner's Manual
ALWAYS turn the power wheelchair power OFF and engage the motor locks/clutches to
prevent the wheels from moving BEFORE attempting to transfer in or out of the power
wheelchair. Also make sure every precaution is taken to reduce the gap distance.
DO NOT engage or disengage the motor locks/clutches until the power is in the OFF position.
DO NOT operate on roads, streets or highways.
DO NOT climb, go up or down hard surface ramps greater than allowed in specifications.
Use special caution on soft surfaces as they greatly reduce incline rating. See specifications
for your power wheelchair.
DO NOT attempt to move up or down an incline with a water, ice or oil film or loss of
control & braking will result.
DO NOT attempt to drive over curbs or obstacles greater than maximum climbing capability
shown in specifications . Doing so may cause your power wheelchair to turn over and
cause bodily harm or damage to the power wheelchair.
DO NOT use unauthorized parts, accessories, or adapters other than those authorized by
ConvaQuip Ind., Inc.
DO NOT attempt to lift the power wheelchair by lifting on any removable (detachable)
parts. Lifting by means of any removable (detachable) parts of a power wheelchair may
result in injury to the user of damage to the power wheelchair.
DO NOT stand on the frame of the power wheelchair.
DO NOT use the footplate as a platform. When getting in or out of the power wheel-
chair, make sure that the footplate is in the upward position or swing footrests towards the
outside of the power wheelchair. See section of manual titled Getting On and Off the
Power Wheelchair.
ALWAYS wear your lap belt.

HOSS - Owner's Manual 9
ELECTRICAL
EXTREME care should be exercised when using oxygen in close proximity to electric
circuits. Contact your oxygen supplier for instruction in the use of oxygen.
Grounding instructions:
DO NOT, under any circumstances, cut or remove the round grounding prong from any
plug used with or for ConvaQuip products. Some devices are equipped with three-prong
(grounding) plus for protection against possible shock hazards. Where a two-prong wall
receptacle is encountered, it is the personal responsibility and obligation of the customer to
contact a qualified electrician and have the two-prong receptacle replaced with a properly
grounded three-prong wall receptacle in accordance with the National Electrical Code. If
you must use an extension cord, use ONLY a three-wire extension cord having the same or
higher electrical rating as the device being connected. In addition, ConvaQuip Ind., Inc.
has placed RED/ORANGE WARNING TAGS on some equipment. DO NOT remove
these tags. Carefully read battery/battery charger information prior to installing, servicing or
operating your wheelchair.
RAIN & MOISTURE
ConvaQuip Ind., Inc. has established the following rules for dealing with moisture.
End user or their attendant should allow sufficient time to remove his/her power wheelchair
prior to a rain storm or inclement weather to retain wheelchair operation.
DO NOT leave your power wheelchair in a rain storm of any kind.
DO NOT use your power wheelchair in a shower or leave it in a damp bathroom while
taking a shower.
DO NOT leave your power wheelchair in a damp area for any length of time.
Direct exposure to rain or dampness will cause the wheelchair to malfunction electrically
and mechanically; may cause the wheelchair to prematurely rust.
Check to ensure that the batteries are secured in place, the joystick boot is NOT torn or
cracked where water can enter and that all electrical connections are secure at all times.
DO NOT use the joystick if the boot is torn or cracked. If the joystick boot becomes torn
or cracked, replace IMMEDIATELY.

10 HOSS - Owner's Manual
WEIGHT TRAINING
ConvaQuip Ind., Inc. DOES NOT recommend the use of its power wheelchair as a
weight training apparatus. Power wheelchairs have NOT been designed or tested as a
seat for any kind of weight training. If occupant uses said wheelchair as a weight training
apparatus, ConvaQuip Ind., Inc. shall NOT be liable for bodily injury and the warranty will
be voided immediately.
SAFETY/HANDLING OF POWER WHEELCHAIRS
“Safety and Handling” of the wheelchair requires the close attention of the wheelchair user
as well as the assistant. This manual points out the most common procedures and tech-
niques involved in the safe operation and maintenance of the wheelchair. It is important to
practice and master these safe techniques until you are comfortable in maneuvering around
the frequently encountered architectural barriers.
Use this information only as a “basic” guide. The techniques that are discussed on the
following pages have been used successfully my many.
Individual wheelchair users often develop skills to deal with daily living activities that may
differ from those described in this manual. ConvaQuip Ind., Inc. recognized and encour-
ages each individual to try what works best for him/her in overcoming architectural ob-
stacles that they may encounter. Techniques in this manual are a starting point for new
wheelchair users and assistants with “safety” as the most important consideration for all.
STABILITY AND BALANCE
WARNING
Always wear your lap belt.
To assure stability and proper operation of your wheelchair, you must at all times maintain
proper balance. Your wheelchair has been designed to remain upright and stable during
normal daily activities as long as you do not move beyond the center of gravity.
The anti-tip wheels are normally positioned approximately two inches off the ground (with a
rider in the chair) but may be adjusted in height downward by your dealer. Because your
power wheelchair is a "midi" (3/4) drive chair the anti-tip wheels are normally only used
when braking going forward down a steep incline. Reducing this setting causes the power-
chair to tilt forward at a lesser angle before resting on the anti-tip wheels if you decelerate
rapidly while going down a hill. The normal adjustment should allow the power wheelchair
to climb a two inch obstacle.
DO NOT lean forward out of the wheelchair any further than the length of the armrests.

HOSS - Owner's Manual 11
STAIRWAYS - WARNING
DO NOT attempt to move an occupied power wheelchair between floors using a stairway
or escalator. Use an elevator to move an occupied power wheelchair between floors. If
moving a power wheelchair between floors by means of a stairway, the occupant MUST be
removed and transported independently of the power wheelchair Again, DO NOT use an
escalator to move a wheelchair between floors. Serious bodily injury may occur..
Extreme caution is advised when it is necessary to move an UNOCCUPIED power wheel-
chair up or down the stairs. ConvaQuip Ind., Inc. recommends disassembling your wheel-
chair into smaller, more manageable components to keep from personal injury. Lifting by
means of any removable (detachable) parts of a wheelchair may result in injury to the user
or damage to the wheelchair.
Follow this procedure for moving wheelchair between floors when an elevator is NOT available:
ESCALATORS - WARNING
DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur.
TRANSFERRING TO/FROM OTHER SEATS
WARNING
ALWAYS turn the wheelchair power OFF and engage the motor locks/clutches to prevent
the wheels from moving BEFORE attempting to transfer in or out of the wheelchair. Also
make sure every precaution is taken to reduce the gap distance. Always have an attendant or
healthcare professional present while learning to properly transfer yourself.
CAUTION
When transferring, position yourself as far back as possible in the seat. This will prevent
damaging the upholstery and the possibility of the wheelchair tipping forward. See section
Getting On and Off the Power Wheelchair.
PERCENTAGE OF WEIGHT DISTRIBUTION
WARNING
DO NOT attempt to reach objects if you have to move forward in the seat or pick them up
from the floor by reaching down between your knees.
Many activities require the wheelchair user to reach, bend and transfer in and out of the
wheelchair. These movements will cause a change to normal balance, center of gravity, and
weight distribution of the wheelchair. To determine and establish your particular safety
limits, practice bending, reaching and transferring activities in several combinations in the
presence of a qualified health professional BEFORE attempting active use of the wheel-
chair. Remember. . . Keep your lap belt on at all times.
Never roll backward down an incline as caster rotation reduces rearward stability.

12 HOSS - Owner's Manual
REACHING, LEANING, BENDING AND BENDING - FORWARD
Position the rear casters so that they are extended as far rearward as possible and engage
motor locks/clutches. DO NOT LEAN FORWARD OF THE ARMRESTS.
REACHING, BENDING - BACKWARDS
WARNING
DO NOT lean over the top of the back upholstery. This will change your center of gravity
and may cause you to tip over.
Position wheelchair as close as possible to the desired object. Point rear casters rearward
to create the longest possible wheelbase. Reach back only as far as your arm will extend
without changing your sitting position.
Persons having disabilities which limit their ability to remain erect without assistance,
(stroke patients, severe muscular diseases, etc.) should carefully evaluate whether they
should operate a wheelchair at all. If they decide, with the advise of their physician or
another advisor, that they are capable of safely operating a wheelchair, they should consider
the use of a bicycle helmet or pads when operating a wheelchair. These articles would help
protect them should they find themselves in a hazardous situation where they could tip over
or fall because of their lack of balance.
DIFFERENT STYLES OF POWER WHEELCHAIRS HAVE DIFFERENT INCLINE CLIMB-
ING ABILITIES. CAREFULLY STUDY THE CHART TO SEE THE CORRECT SPECIFI-
CATIONS FOR YOUR UNIT. DO NOT EXCEED THE SPECIFICATIONS OF THE POWER

14 HOSS - Owner's Manual
Getting On and Off The Power Wheelchair
The following is a recommended method for getting on your Power Wheelchair
1. The wheelchair should be stopped on a flat, level surface with the power
switch in the OFF position (no visible lights).
(SEE WARNING BELOW)
2. Raise the foot rest plate so that you may back up to the wheelchair
squarely. WARNING: Do not use the footplate as a platform. When getting in
or out of the wheelchair make sure that the footplates are in the upward posi-
tion or swing footrest towards the outside of the wheelchair.
We realize that many bariatric persons can not do a side transfer or raise their legs to raise and
lower the footplate. If and only if you must step on the footplate for entering or exiting the
Hoss, you must follow these instructions. Your power wheelchair is equipped with a patented
infinitely adjustable rigid anti-tip system. When both of the front anti-tip wheels are lowered to
contact the floor, you can step on the platform without tipping the chair forward. After entry
the wheels must be raised to adjust to the driving environment - 1/4” for flat floors and 2” for
outdoor terrain. Always keep the adjustment as low as possible for your driving area. Warn-
ing: Failure to lower the anti-tip wheels for entry and exit will result in the chair tipping for-
ward when you stand on the footplate which can cause you to fall and result in possible
serious injury. Warning: As with any wheelchair part should the anti-tip assembly become
damaged, discontinue use immediately and contact your dealer for service.

HOSS - Owner's Manual 15
3. Position yourself squarely in front of the seat and lower yourself into the seat using the
armrests if necessary. (Never use the control housing or joystick as a support while getting
on and off the wheelchair.)
4. Lower the footrest and place your feet securely on the footrest.
5. Buckle the safety belt around yourself belt to help hold yourself securely in the chair.
6. Push the power button on the speed control, the LED lights should activate.
7. When seated comfortably, you can drive the power wheelchair.
The method for getting off is the reverse procedure.
1. Turn the power switch OFF when stopped (no visible lights).
2. Unfasten your safety belt and raise (or have someone raise) the footrest bracket.
3. Make sure your feet are planted firmly on the ground and stand up.
WARNING
Keep the power button in the OFF position at all times when stopped or when getting on
or off the wheelchair. Sudden accidental movement of the wheelchair will be avoided
with the power switch in the OFF position.
Tipping can occur if you get on the power wheelchair in a manner other than recommended.
Tipping can be avoided by keeping your weight away from the outer edges until seated. If you
step into the wheelchair, sit directly in the center of the seat, not near the edge. Tipping, loss of
control or traction (wheel spin) can also occur if you turn the joystick sharply while traveling at
or near full throttle and on slick surfaces or inclines.

Pushing the Control
Knob straight for-
ward will cause the
wheelchair to move
in a forward direc-
tion. Your speed is
determined by how
far forward you
push the control
knob and by the
speed control set-
Moving the knob directly
to the left (while station-
ary or moving) will cause
the chair to turn to the left.
Conversely, moving to the
right will cause it to turn
right. If you are station-
ary, the chair will tend to
rotate where it sits. You
may use this to position
your self in place, or to
ting (# 2). Pulling back on the knob causes
the wheelchair to move in the reverse di-
rection

The difficult part of controlling a power wheel-
chair is all of those moves in between the four
main directions. Shown here are different direc-
tions for turning the wheelchair as you operate
the vehicle, but remember these moves may be
anywhere in between, it depends on the direc-
tion of travel required at the time. The impor-
tant thing to remember is that in the forward
positions, the joystick is like a pointer, point and
that is the direction you will go. In reverse, the
pointer is indicating the direction the front of
the wheelchair will go, not the back. The best
thing to do is learn to operate your power wheel-
chair in a large flat open space, and practice
making the chair move in the direction you de-
sire.
METHODS FOR CONTROLLING THE DIRECTION OF
YOUR HOSS POWER WHEELCHAIR.
In an emergency or a "Quick-Stop" situation, you may pull straight back
on the control knob momentarily to cause the motors to apply reverse
current and stop quickly. Use extreme caution, as this may cause your
body to pitch forward in the chair. Always wear your lap belt.
