Warranty

Foredom warrants its product to be free of

defects in material or workmanship for a

period of one year after purchase. During

the warranty period, the defective product

will be repaired or replaced without

charge or, at our option, the purchase price

will be refunded. This warranty does not

cover damage caused in transit or by

accident, misuse, or ordinary wear.

ALL IMPLIED WARRANTIES, INCLUDING

BUT NOT LIMITED TO WARRANTIES OF

FITNESS AND MERCHANTABILITY, ARE

HEREBY LIMITED IN DURATION TO A

PERIOD ENDING ONE YEAR FROM DATE

OF PURCHASE, AND

LIABLE OR RESPONSIBLE FOR ANY

SPECIAL OR CONSEQUENTIAL DAMAGES.

Micromotor Accessories

The K. 1070 Micromotor Kit comes with a

chuck wrench and chuck joint wrench for

changing collets, a spare fuse, and spare

pair of motor brushes as shown in Figure 6.

Installing/Changing Collets

The Handpiece comes with a 2.35mm

(3/32

″)

collet installed. Optional 1/8

″ and

3mm collets are available separately . They

can be installed with the collet changing

wrenches, described below.

Caution: Finger tightening is not

enough. A wrench must be used to

tighten the collet fully several turns

beyond the point of initial resistance.

If collet is too loose or absent, spindle

will not turn and damage will occur.

1. With a test bur in the collet, turn the

Locking Ring toward the secure“S” (closed)

position (see Figure 4 on reverse.)

2. Place the octagonal hole of wrench over

the brass nose cone and unscrew the nose

cone assembly from the handpiece body

(shown in

Figure 7.) Do

not remove

locking ring

or spring.

Repair Services

Authorized repair service is available at the

Foredom factory in Bethel, CT. Send items for

repair to the factory marked “Attention:

Repair Department”. Enclose the item(s), a

packing list, and information regarding the

problem or repairs required. Estimates of

repair cost will be made upon request. It is

our policy not to proceed with a repair

without your approval if the cost (labor plus

parts) is more than fifty percent of the cost

for a new replacement. You will be notified

and advised of the cost to repair and to pur-

chase a new replacement. Please allow three

business days for an estimate to be done and

five to seven business days for repair work

to be completed after we receive your

Carbon Brushes continued

3. Reinsert brush assembly or new

assembly into brush tube. Replace and

tighten screws.

4. Screw protective cap back onto rear

of motor housing so that top of brush

assembly is completely tightened.

5. If new brushes were used, run the

handpiece for 30 minutes at half-speed

no load to confirm proper function,

before use.

Maintenance

The H.MH-170 has permanently lubricated

ball bearings that do not require lubrica-

tion. Putting even a small amount of oil

into the handpiece can damage it.

Cleaning Handpiece

Use the Handpiece in as clean and dust

free an environment as possible.

If the Micromotor Handpiece is used

for woodcarving, it should be cleaned

after every use.

With handpiece power

cord disconnected from control box, unscrew

the protective cap (see Figure 5) and use a

clean cloth to wipe dirt, chips or dust off

from the exhaust ports and inside the cap.

A cloth with a small amount of alcohol

solution can be used to clean the outside

of the handpiece if necessary.

Do not use any other cleaning fluids

or immerse handpiece in any liquid.

The H.MH-170 Handpiece is

not autoclaveable.

Checking/Changing

Carbon Brushes

A spare set of carbon brushes is supplied

with each handpiece. Depending on how

long the handpiece is used each day, the

brushes should be checked for wear

periodically (about every

200 hours of use)

and replaced when the brush is less than

2mm (5/64

″) long.

1. With handpiece power cord disconnected

from control box, unscrew protective cap

from rear of motor (see Figure 5) by

turning in counterclockwise direction while

gripping the handpiece body. (It has a

standard right hand thread.)

2. With small crosspoint screwdriver remove

screws and brush assemblies one at a time

when reusing existing brushes. Check length

of carbon brush from spring to curved

side of brush.

Brushes should be r

emoved,

and

eplaced (if less than 2mm in length)

one at a time.

Pay careful attention to the orientation of the

brush curve in relation to the curve of the

motor armature. This same orientation must

be maintained when replacing brushes.
