ASSEMBLY AND OPERATING INSTRUCTIONS
NOTE: For additional references to the parts listed below, refer to the Assembly Dia-
gram (page 8).
To Mount The Tire Patching Machine On A Workbench:
1. Caution: Make sure the Tire Patching Machine is securely mounted on a flat,
level, sturdy, workbench capable of supporting the weight of the Tire Patching
Machine, tools, accessories, and work piece.
2. There are two 1/2” wide mounting slots located at the bottom right and left sides
of the Main Frame (part #3). (See Assy. Diagram.)
3. With assistance, set the Tire Patching Machine in the desired location on the top
of the workbench. Using the two mounting slots as a template, mark the two
holes that are to be drilled through the top of the workbench. Then, temporarily
remove the Tire Patching Machine.
4. Using a drill and 1/2” drill bit (not provided), drill the two previously marked holes
completely through the top of the workbench.
5. Align the two 1/2” mounting slots at the right and left ends of the Main Frame
(part #3) with the two previously drilled holes in the workbench. Then, firmly
secure the Tire Patching Machine to the workbench with two appropriate length
1/2” bolts, two lock washers, and two nuts (not provided).
To Prepare The Tire Tube For Patching:
1. Carefully remove the tube valve stem from the tire tube, and allow all of its air to
escape. Then, remove the tube from the tire.
SKU 46616 PAGE 5 REV 03/04

2. Firmly screw the tube valve stem back into the tire tube. Then, re-inflate the tube
according to the tire tube manufacturer’s recommended PSI air pressure.
3. Fully submerge the tire tube in a tank of water, and observe air bubbles escaping
from the hole in the tube. Then remove the tube from the water tank and, with
chalk, mark the location of the hole.
4. Carefully remove the tube valve stem from the tire tube, and allow all of its air to
escape.
5. Using sandpaper, or a scraper made especially for this purpose, rough up the
area around the hole.
To Operate The Tire Patching Machine:
1. Apply an all-purpose, fast dry, rubber cement on the area around the hole. Make
sure to allow the cement to dry. Then, apply the prepared side of an
appropriate size tube patch to the tire tube (the side with the colored peel-off).
2. Place the tire tube on the Heating Box Cover (part #7) of the Tire Patching
Machine. Make sure the tube patch is resting downward, directly on the
surface of the Heating Box Cover. (See Assy. Diagram.)
3. Turn the Handle (part #16) clockwise to lower the Press Plate (part #4) until the
tire tube is held firmly in place between the Heating Box Cover (part #7) and the
Press Plate. (See Assy. Diagram.)
4. Connect the Power Cord/Plug (part #17) to a grounded, 3-prong, 120 volt,
electrical outlet. (See Assy. Diagram.)
5. Turn the Switch (part #19) to its “ON” position. (See Assy. Diagram.)
6. Allow 20 to 30 minutes for theTire Patching Machine to heat up and firmly
adhere the tube patch to the tire tube.
7. Then, turn the Switch (part #19) to its “OFF” position, and disconnect the Power
Cord/Plug (part #17) from its electrical outlet. (See Assy. Diagram.)
8. Turn the Handle (part #16) counterclockwise to fully raise the Press Plate (part
#4), and remove the tire tube from the Tire Patching Machine. (See Assy.
Diagram.)
9. Firmly screw the tire tube valve stem back into the tube. Then, re-inflate the tube
according to the tire tube manufacturer’s recommended PSI air pressure.
SKU 46616 PAGE 6

10. Fully submerge the tire tube in a tank of water to make sure no air bubbles are
escaping from the tube. If no air bubbles are observed, the tire tube has
been successfully patched.
11. Carefully remove the tube valve stem from the tire tube, and allow all of its air to
escape. Then, re-install the tire tube in the tire.
INSPECTION, MAINTENANCE, AND CLEANING
1. CAUTION: Always disconnect the Tire Patching Machine from its electrical power
source before performing any inspection, maintenance, or cleaning.
2. BEFORE EACH USE, inspect the general condition of the Tire Patching
Machine. Check for loose screws, misalignment or binding of moving parts,
cracked or broken parts, damaged electrical wiring, any other condition that may
affect its safe operation. If abnormal noise or vibration occurs, have the problem
corrected before further use. Do not use damaged equipment.
3. PERIODICALLY, use a premium quality, lightweight machine oil to lubricate all
moving parts.
4. When necessary, wipe with a damp cloth, using a mild detergent or mild solvent.
