When adjusted correctly:

— There should be approximately

⁄

" free

play at foot pedal.

— When fully applied there should be no

less than 1" clearance between floor and

lowest part of pedal.

IMPORTANT:

If foot brake pedal contacts

floor when applying, full braking will not

occur.

When satisfied with your adjustment,

tighten nuts and close lower door before

adjusting brake micro switch.

If it is suspected that electric brake (see

Figure 84) on motor requires service or

repair, motor assembly must be taken to

a motor service shop that is familiar with

motor brake service and repair.

Figure 84. Motor brake system.

Spindle Motor

Electric Motor Brake

Brake Service

This lathe has two braking systems. One is a

non-adjustable electric motor brake located at

the tail-end of the spindle motor (see Figure 84);

the second is an adjustable band and hub brake

connected to the pulley end of the motor (see

Figure 83).

When the user presses the foot pedal, mechanical

linkage pulls on a brake band that applies

friction to one side of the polished V-belt drive

hub. As the brake band wears, the adjustment is

made at the threaded stud. When the brake band

becomes worn to the point where the rivet heads

are no less than 0.005" away from contacting the

hub, then brake band replacement is required.

Tools Needed

Open-End Wrench 14mm .....................................1

DISCONNECT LATHE FROM POWER!

Put on a respirator and eye protection to

protect yourself from hazardous brake dust.

Remove motor access plate below outboard

chuck.

Using a vacuum with HEPA filter, remove

any built-up brake and belt dust.

If brake band is worn and requires

replacement, un-thread stud end, disconnect

spring at brake band anchor eye (see Figure

83) and install a new brake band.

At brake band adjustment stud, use a 14mm

wrench to adjust nuts and pull brake band

closer to hub.
