Your CardioAccelerator is now ready to be used. With armrest locking pin removed, place
forearms on armrests (see section “D”, pg.9 for correct armrest height before using)
applying pressure on forearms. Alternating between your left and right arms, move hands up
and down in a reciprocating motion pivoting at your elbows. This is a motion similar to doing
curls with weights in your hands. Once handgrips are lifted until they stop, push handgrips back
down until they stop (still rotating around the pivot point of elbows applying downward force
on forearms).
CARE SHOULD BE TAKEN TO USE THE RECIPROCATING ARM MOTION EXERCISE ONLY ON
LEVEL WALKING SURFACES.
C. Use of CardioAccelerator
9
Note: Use of the dual motion reciprocating resistance arm exercise on your CardioAccelerator,
while walking, can raise your heart rate by an additional 10–30 beats per minute for a more
robust cardio workout. The dual motion arm resistance workout activates many muscle
groups including, but not limited to, biceps, triceps, forearm, shoulder, and many back
muscles. Since muscle loss of up to 3% a year can occur as one advances over the age of 50,
resistance exercise is an important element of maintaining muscles for a healthier life. In
addition, the National Institues of Health suggests improved health through regular walking.
We encourage you to use mobility as medicine.
Health Benets
If you desire to use your UPWalker CardioAccelerator
as a traditional mobility assist device, without arm
exercises, insert the armrest locking pin in hole
indicated with white circle (Fig C1) which secures
your armrest in a ergonomically comfortable 14
degree angle. See pg. 9 “Reinserting the armrest
locking pin”.
Fig C1
Use of CardioAccelerator as a Traditional Upright Rollator
Once standing in the UPWalker, move forward so your body is between the armrest pads,
standing in an upright position with good posture. Put equal arm pressure on the left and
right armrest pads. Put hands on handgrips with ngers around the brake handles. Take
full-stride steps with constant gait. Pull on brake handles while going down hills to control
speed. Walk regularly for exercise to maintain good health.

The armrests on the UPWalker are raised and lowered independently of each other. It is
recommended that the armrests be set at the same height. Should the user have a physical
condition that requires offsetting the height of the armrests, the armrests can be set
accordingly for comfort.
D. Setting Desired Armrest Height
10
Fig D1
Fig D2
To raise and lower the armrests, rst push in the
Iight gray height adjustment tab (Fig D1) and, while
keeping the tab depressed with one hand, use your
other hand centered over armrest pad to raise or
lower the armrest to the desired height (Fig D2).
When the armrest is at the desired height, release
the height adjustment tab to automatically engage
the tab's pin in the tube hole. You will hear a "click"
when the tab is engaged. Avoid pinching your
ngers between the armrest and the top of the
height adjustment tube while raising or lowering
the armrests.
CHECK THAT THE HEIGHT ADJUSTMENT TABS
ARE SECURELY IN PLACE BEFORE PLACING
WEIGHT ON THE ARMRESTS AND WALKING IN
THE UPWALKER.

1.
Reinserting the Armrest Locking Pin
A two–stage approach to fully inserting the locking pin makes it easier. First, move the
handgrip up and down slightly while inserting the locking pin with light pressure into in the
outer hinge body hole (Fig C1). When the hinge holes line up, the pin will pop through the
midsection of the hinge. It may then seem to hesitate rather than pass all the way through to
the far side of the hinge. At that point, continue to maintain light inward pressure on the pin,
but move the upper handgrip left and right lightly, without applying any more up or down
force. This should enable the pin to line up with the next hole, then pop all the way through
the hinge. There is a vertical white line which should be inline with height adjustment tube to
assist in aligning holes.
If you are still having trouble with reinserting the locking pin, unlock the cam (Fig B6) that
secures the upper handle angle. Pivot the upper handle outwards to a slightly less inwardly
slanted angle (towards a slightly more vertical position). Lock the cam. Then repeat the
procedure explained in the above paragraph.
DO NOT USE THE WALKER UNLESS THE LOCKING PIN IS ALL THE WAY THROUGH THE HINGE;
OR ALL THE WAY OUT.

Handgrips are designed to be turned in slightly
from a vertical position for ergonomic comfort. To
secure handgrips from moving or to set and secure
handgrip at the appropriate angle, open the
chrome cam lever under the armrest pad (Fig E1).
Once the preferred angle is established, close the
chrome cam lever rmly to secure the handgrip
in place (Fig E2). The tightness of the cam lever
can be adjusted by turning the cam lever nut on
the outer side of the armrest.
E. Securing Handgrips
The UPWalker includes a convenient height
adjustment memory stop on the bottom of each
height adjustment tube (Fig D3). After you have
established your preferred height setting, unlock
the height adjustment memory stop using the gray
knob, turning it in a counterclockwise
direction. Slide the memory stop up to the frame
and relock in place by turning the gray knob in a
clockwise direction until tight. Once set you may
raise an armrest from a lowered position until the
memory stop is reached. The memory stop does not
need to be moved again unless a different
armrest height is required.

The armrest should be set at a height that is high enough that you feel support under your
forearms when standing upright inside the UPWalker but not so high as to cause your
shoulders to "hunch." Put equal weight on each forearm while using the UPWalker. You may
nd it benecial to displace some of your body weight on your forearms while walking.
Each setting is marked with a number on the height adjustment tube for future reference.
Note and remember the setting you prefer.

To set parking brake, push the brake handle
forward until it clicks in locked position. Some
users may want to hold the hand-grip with one
hand while using the other hand to push the brake
handle forward. (Fig F1).
To unlock brakes, simply pull brake handles back
toward you.
The following information is intended to assist
you with the adjustment of your brakes.
Note: The brakes on your new UPWalker have been
preset from the factory. Due to normal use over time
you may need to make adjustment to maintain this
setting. You can adjust the brakes by making the
following adjustments at either the brake handle
position (Fig G1 ) or above the rear wheel (Fig G2 ).
Before attempting to adjust the brakes, ensure that
the parking brake is disengaged (see “How to Use
Parking Brakes” above).

It is strongly recommended that the parking brakes be set in the locked position when the
user is sitting down in the UPWalker or standing from a seated position and when the user is
making adjustments to the UPWalker's settings.
When using brakes while walking, both brakes should be applied with equal pressure.

Brake is Too Loose
Use ngers or pliers to turn the barrel adjuster nut
counterclockwise a half rotation (Fig G3). Try the
brake. If this does not correct the problem, repeat
turning the barrel adjuster nut a half rotation at a
time until the brake functions as expected. Then
turn the larger locking nut clockwise using ngers
or a 10 mm or 13/32 wrench until it presses tightly
against the housing to prevent the barrel adjuster
nut from loosening.
Resetting the Brakes
NOTE: DO NOT ATTEMPT TO PERFORM THIS TASK IF YOU ARE NOT
MECHANICALLY INCLINED.
If you cannot achieve the desired adjustment by
means of the above, you may use a 4 mm or 5/32"
Allen wrench to reset the brake using the brake
cable nut attached to the brake pad at each rear
wheel (Fig G4). First loosen the nut by turning Allen
wrench counterclockwise. Once loosened, you may
pull the brake cable out of the nut to tighten the
brake, or push the brake cable into the nut to
loosen the brake. After achieving desired cable
length, tighten the nut by turning clockwise. You
may have to repeat adjustment a few times to get
it right.
Fig G3
Fig G4
Brake is Too Tight
Use ngers or a 10 mm or 13/32 wrench to turn the larger locking nut counterclockwise
until loosened. Then use ngers or pliers to turn barrel adjuster nut clockwise a half rotation
(Fig G3) and try the brake. If this does not correct the problem, repeat turning the barrel
adjuster nut a half rotation at a time until the brake functions as expected. Then turn the
locking nut clockwise until it presses tightly against the housing to prevent the barrel
adjuster nut from loosening.
If you are not comfortable with adjusting your brakes please consult a local Durable Medical
Equipment dealer or contact LifeWalker Customer Service at 866-588-1845 or
[e-mail]. Please note, LifeWalker does not reimburse
customers for maintenance charges on the UPWalker, including brake adjustments.

For most users the front wheels should be set to
pivot freely and allow the UPWalker to turn left and
right. This is achieved by placing the light gray tab
above each front wheel in the down position (Fig J1).
However, the front wheels can be locked to roll only
in a straight line by ipping the gray wheel lock tabs
to the up position (Fig J2).
The rear wheels should be kept in the locked
position when using the UPWalker. If you need to
unlock the rear wheels to reduce the size of the
unit for shipping, storage or transport, lift up the
black wheel lock tabs above the rear wheels (Fig J3)
and pivot the wheels inward. Push wheel lock tabs
down to closed position after turning wheels under
the UPWalker.
K. Closing the UPWalker
Lower the armrests to the lowest setting (see
"Setting Desired Armrest Height" on page 9). Lift
the seat up by seat lift handle (Fig Kl) and allow
UPWalker to fold in (Fig K2). Stand the UPWalker on
all four wheels to roll or stow. Use the buckle strap
