Set-Up Notes
1. The CH-22 Multi-Tire Changer must be mounted to a solid, level surface, in a clean working
environment and with necessary clear access around the unit.
2. TSI has developed an optional Stand and Floor Plate which assemble into a convienient
package to raise the CH-22 for better handling, provide a tire Bead Breaker and include a
stable platform (see page 7).
A. The CH-23 Stand raises the CH-22 to a good working height, provides a very handy
Bead Breaker and tool storage.
B. The Floor Plate (PN 6192) provides a non-slip surface for the technician.
C. Assemble the three items and then bolt them to the oor
3. Loosen the tire bead before using the CH-22 Multi-Tire Changer
Operating Instructions
Determine the tire size being serviced and set
the jaw clamps (see Fig. 2) accordingly.
Put the pins in matching holes on the two arms
with the free-moving jaw clamps. Slide the jaw
clamps against the pins.
Fig. 2Fig. 2
For best results, have the longer area of the rim
facing down for the jaw clamps. (See Fig. 3)
Most the time the valve stem will be up and
accessible. If not, mount the tire and later ip it
over to connect an air hose to the valve stem for
adding air.

Adjust the moveable jaw clamp using the
threaded rod assembly (see Fig. 4) so the tire
ange clears each of the jaws. Ideally the rim
should be centered over the center hole on the
Tire Changer.
Operating Instructions
Fig. 4Fig. 4
Fig. 5Fig. 5
Before tightening the rim, determine the largest
center post to t in the wheel hole (see Fig. 5).
Each post has two sizes.
Make sure to secure the edge of the rim and
tighten the adjusting clamp to secure the
wheel.
Fig. 6Fig. 6
Lubricate the tire and entire rim ange area
around the tire before mounting or dismounting
the tire (see yellow arrow in Fig. 5). Be sure to
use lubricant intended for tire and rim.

Operating Instructions
Make sure the tire bead is in the “drop center”
of the rim for this process. Press and hold with
one hand while prying the Mongoose Tire Tool
around the center post.
Demount deated tire using the “rod end” of
the Mongoose Tire Tool (see Fig. 7). The ball-
end is pushed under the top bead and rested
on the rim as illustrated. While holding the
Mongoose Tool against the center post with
one hand, and lifting up on the tire with the
other, rotate the tool full circle. Demount the
bottom bead the same way.
Vary the angle of the Mongoose Tire Tool
against the center post can achieve better
results for each user based on the different rim
or tire sizes and the shapes of each.
Fig. 7Fig. 7
Mounting the tire uses the "at-end" of
the Mongoose Tire Tool (see Fig. 8). While
applying pressure to the low side of the tire
(always facing the operator) place the ball-
end between rim and bead. With the at side
against the center post rotate the tool full circle
for both bottom and top beads.
Remember to use lubrication on the rim and
tire bead.
Optional Demount Tool (PN 12489)
To protect chrome or aluminum rims from tool
scrapes use this handy plastic accessory with
the regular size Mongoose Tire Tool or the the
Mini Mongoose Tire Tool.
Hold the Demount tab on the Mongoose Tire
Tool. Push down and into the tire ange/bead
area (see Fig. 9).

Operating Instructions
Insert the Demount tab into the rim ange
area (see Fig. 10). With your other hand guide
the tire beads into the “drop center” of the
rim opposite the side where you've placed the
Mongoose Tire Tool and demount tab.
Optional Mount Tool (PN 12488)
Fig. 12 shows optional PN 12488 Mount tab
with the Mongoose Tire Tool. Place the tire over
the rim and plunge the two tools over the edge
of the rim (see Fig. 13). Use the Mongoose Tire
Tool to pry against the center post in a circular
motion to mount the tire.
Fig. 10Fig. 10
Fig. 11Fig. 11
Fig. 12Fig. 12
Fig. 13Fig. 13
Repeat for both sides of the tire. Upon
mounting the tire wipe off the lubricant and
clean the tools and tire.
Loosen the Handle and Threaded Rod
Assembly to remove the tire.
USE LUBRICANT AND BE CAREFUL TO
AVOID PINCHING FINGERS
Pry up on the Mongoose Tire Tool and demount
tab in an arced motion so they rest on the rim
as shown in Fig. 11. With the tool against the
center post rotate them in a circular motion
around the post until the tire is free from the
rim.
Do this for both tire beads until the tire is
completely demounted.
