YOU MUST SUPPLY THE OWNER WITH THIS MANUAL

• This product is for INDIVIDUAL USE only.

• As with any new physical activity, instruction, practice, and common sense are

necessary for successful use of the TKW. Practice turns slowly until you get the

“feel” of your unit.

• Reckless usage of this product includes, but is not limited to, scooting too fast,

sitting/standing on knee pad, attempting extreme maneuvers around corners or

in recreational environments.

• Be sure that the knee platform height adjustment knob is tightened and fully

engaged before each use.

• Be sure the upper steering post and height adjustment knob are tightened and

fully engaged before each use.

• Be sure hand brakes are fully operational and engage the rear wheels when the

handles are squeezed or locked.

• Be sure you are on a level surface and not on any incline when you mount or

dismount.

• The hand brake is designed to maintain a stopped stance and is NOT intended to

be used for stopping the unit while you are moving.

• Use of the hand brake while in motion may cause an abrupt stop. Your uninjured

foot should be used to propel and to stop the unit.

• This unit is intended for use with a person properly positioned on the knee

platform.

• ALWAYS use caution when moving from carpeted to hard surface oors, rough

surfaces or when changing levels (for example, moving from a curb to the street

and back onto the sidewalk).

• DO NOT operate the TKW on or near stairs or escalators, over bumps, on hills, or

while using mind-altering drugs or alcohol, or while suffering from dizziness.

• DO NOT sit or stand on the knee platform, or use the TKW to pull yourself up

from a seated or other position. The knee platform is not designed for sitting or

supporting full body weight.

• DO NOT attempt to reach objects if you are kneeling on the knee pad.

• DO NOT hang anything from the frame of the unit. Items should be placed in the

basket (optional) designed for your unit (available from your provider).

Some of the above situations will cause a change of weight distribution and may

cause the unit to tip, resulting in injury or damage. Always use EXTREME caution

when reaching for any object.

SAFETY INSPECTION - MAINTENANCE

Your product is a precision product - proper care will ensure proper function. Regular

cleaning will reveal loose or worn parts. DO NOT over tighten parts or hardware,

as doing so can damage the frame. DO NOT operate the product if there are any

missing parts or hardware. You should have a dealer or qualied professional perform

maintenance on your product at least once every six months, or immediately if you

notice any item needing service. Frequent use likely means that your product will

require more maintenance than we suggest. In anticipation of and after any excessive

use, we recommend that you perform a complete safety inspection including all items.

Assembly Instructions

Included Items

Allen wrench, at wrench, folding hinge bolt, locking washer, nut

(see Figure 1).

Steering Column Assembly

Carefully remove from the shipping box; remove all packing materials and locate the

tools and hardware pictured (see Figure 1). The upper steering post will be separated

from the unit for transport and will need to be attached to the frame before using the

TKW. Use the included tools and parts to complete this step.

1 Push the lever to the right so that the pin is ush with the side of the lower

steering post (see Figure 2).

2 Place the upper steering post onto the lower steering post and slide the lever

to the left so that the pin engages into the hole on the steering posts (see

Figure 3).

3 While holding the upper steering post with one hand, insert the folding hinge

bolt into the hole located on the rear of the steering post until the threads are

exposed on the opposite side (see Figure 4).

4 Place the locking washer and the nut onto the screw and hand tighten (see

Figure 5).

5 Use the Allen and at wrench to tighten the screw. Test the steering post to

make sure it can fold down with a small amount of resistance and holds the

steering post rm when in the engaged position. Adjust the tightness of the

screw, if necessary.

6 Swing the lever upward and push the lever arm down to secure the steering

post to the frame (see Figure 6).

Attaching the Knee Platform

The NOVA Knee Walker can be used for right or left leg injuries.

The offset position of the seat provides better stability and

increased foot clearance for pushing forward. When standing

behind the scooter, the knee platform should be offset on the side

of the non-injured leg (see Figure 7).

1 Remove the height adjustment knob from the frame and

then remove the knee pad from its upside down shipped

position.

2 Insert the knee platform into the frame (see Figure 8).

3 Adjust knee platform to the desired height and insert the screw through the

frame, into the platform, and hand tighten (see Figure 9).

Figure 8 Figure 9

Handle Bar Height Adjustment

1 Remove the height adjustment knob by turning counterclockwise.

2 Adjust the handle bar to the desired height.

3 Insert the screw into the hole on the upper steering post and tighten until

secure.

To Lower the Steering Column (for Transport)

1 Pull the lever arm up to release the clamp, and place the lever in the

downward position.

2 Slide the lever to the right so that the pin disengages from the steering post.

3 Gently guide the steering post downward and position below the seat.

Figure 7

Steering Post Lever Adjustment

The lever located at the base of the steering column should secure the

steering post tightly to the frame so that there is no play or looseness.

The following steps (if necessary) will allow you to adjust the tightness

of the lever if you nd that it is either too hard to push down or too

loose to hold the post securely.

1 Pull the lever arm up to release the clamp, and place the lever

in the downward position.

2 Push upward on the lever until the nut is between the two

sides of the steering post (see Figure 10).

3 Turn counterclockwise to loosen the tension on the lever or

turn clockwise to tighten the tension on the lever.

Brake Adjustment Instructions

To lock wheels - push the brake handle downward until it clicks into the locked position

(see Figure 11).

Brake Adjustments

If you nd it difcult to squeeze/lock the brake handle or that the brake shoe is not

engaging the wheel then you may need to adjust the brake.

1 To Release Tension (make it easier to squeeze or lock): Be sure the brake is

in the unlocked position. Turn the brake adjustment screw counter-clockwise

until the desired tension is achieved. Test after each 1/2 turn. The brake should

lock the wheel when in the locked position. Screw the locking nut against the

brake casing to secure your desired setting (see Figure 12).

2 To Increase Tension (make the brake engage sooner): Turn the adjustment

screw clockwise until the desired tension is achieved. Test after each 1/2

turn. The brake should lock the wheel when in the locked position. Screw

the locking nut against the brake casing to secure your desired setting (see

Figure 12).
