Congratulations on your purchase of the Hudy Micro Tire Truer, the
world's first professional micro tire truer for truing most 1/24 and
1/18 micro car foam tires. Its small size, light weight, and easy
operation make it a great tool to take to every race or practice. And of
course, it gives you the most precise and optimal tire truing available in
a portable package.
This professional-quality micro tire truer features a compact
duraluminum base for a solid, stable platform for truing. Consistent
truing quality is ensured by the grinding drum that is precisely pressed
onto a milled spindle shaft. The grinding spindle, along with the axle
spindle, rides on high-quality shielded ball bearings to eliminate vibration
when truing, while at the same time increasing the truer's operational
life. The grain surface on the grinding drum is uniformly applied, which
stabilizes the drum and eliminates vibration and provides perfect quality
truing. Tire diameter can be easily adjusted on this tire truer, and set
to true numerous tires to the same diameter with a high degree of
precision.
Two other advantages of the tire truer are the collection tray for
ground rubber and a protective cover for the grinding drum. Both these
features enable a safe and clean tire truing process.
MAINTENANCE
After truing, dispose of the ground rubber from the collection tray.
Remove the Grinding Drum Cover (103048) and clean the dust and
rubber from the entire truer with a paintbrush or compressed air.
It is absolutely necessary for all moving parts to move freely. If the truer
is not cleaned, built-up ground rubber will eventually impede operation.
Check the rubber pulley belts periodically for cracking and stretching,
and replace as needed.
IMPORTANT WARNING
• READ these instructions carefully before using
• ALWAYS use protective glasses
• DO NOT touch rotating parts when in use
• DO NOT remove grinding drum protective cover when in use
If you follow these operation and maintenance instructions, HUDY
guarantees high quality, high reliability tire truing as well as a long life
span for this great tool.
We hope that you will be satisfied with the performance and quality of
this equipment. If you have any questions or advice about how to
improve this equipment, please do not hesitate to contact us.
Thank you for choosing HUDY products!

TIRE GRINDING
Before using the tire truer for the first time, adjust the cutting angle by
adjusting the Middle Support Block (103028). Loosen the M4 screw that
secures the middle support block to the base (on the bottom), then
adjust the middle support block until the headstock is parallel with the
grinding drum. This will ensure the grinding plane of the tire is flat and
not coned. Tighten the M4 screw. Use a small amount of medium grade
threadlock compound (for example, Loctite® 242 blue grade threadlock)
on the screw to prevent loosening.
Pivot the Axle Holder (103025) away from the grinding drum by
tightening the Backstop Screw (103054). Fully loosen the Feed
Thumbscrew (103053) from the axle holder, but do not remove it.
Mount the tire by pressing it fully onto the wheel adapter (103210 for
HPI Micro 1/18 or 103220 for Kyosho Mini-Z 1/24). With the truer
turned off, adjust the Backstop Screw (103054) until the tire just
touches the grinding drum. Then, tighten the Feed Thumbscrew
(103053) until it just touches the Thumbscrew Back Post (103033), and
the tire moves slightly away from the grinding drum. You are now ready
to true your first tire.
Turn on the truer, and slowly move the tire toward the grinding drum by
loosening (CCW) the Feed Thumbscrew (103053). When it is loosened all
the way, the tire should be touching the grinding drum, and the Backstop
Screw (103054) prevents the tire from being ground any further. Check
the tire diameter, and if necessary adjust the Backstop Screw (103054)
to make the tire a smaller diameter (loosen screw CCW) or larger
diameter (tighten screw CW). After you have reached the desired truing
diameter, do not move the Backstop Screw (103054) unless you want to
set a different tire diameter. Back the tire away from the grinding drum
by tightening (CW) the Feed Thumbscrew (103053), turn off the truer,
and remove the tire. Repeat this procedure for truing more tires to the
same diameter.
To smooth the surface of a tire while truing, press the Wheelaxle Pulley
(103050) in the axial direction several times.
If you need to change the wheel adapter to true different size tires,
remove the mounted adapter, and then install the other adapter. To
remove the mounted adapter, loosen the adapter setscrew and slide the
adapter off the axle spindle. To install the other adapter, slide the
adapter onto the axle spindle, and then tighten the setscrew onto the
flat spot on the axle spindle. Ensure the adapter is tight on the axle
spindle, and that the assembly does not have excess play.
ELECTRICAL CONNECTION
Connect the power cable to a DC power source (between 7.2V and 12V)
being sure to observe proper polarity; red wire to positive, black wire to
negative. Ensure the drive motor rotates clockwise (CW) when viewed
from the end of the pulley (left side). This will ensure the ground rubber
falls downward into the collection tray beneath the grinding drum.
