Brake Lathes
Installation
1.
Cut the straps securing the lathe to the shipping
pallet. Place the lathe on the bench.
2.
Position the lathe over the four (4) holes indicated
in Fig. 1. Use the four (4) pilot bolts and washers pro-
vided to fasten the lathe to the bench. Wrench tighten
the bolts.
3.
Before plugging the lathe in, be sure the on/off
toggle switch above the drum slide handwheel is in
the OFF position.
READ THE OILING INSTRUCTIONS BEFORE OPER-
ATING THE LATHE.
Figure 1
Electrical Wiring Requirements
The lathe should be electrically grounded to protect
the operator from shock. The lathe is equipped with an
approved 3-conductor cord and a 3-prong grounding
type plug to fit the proper grounding type receptacle.
If your lathe is for use on 115 volts, it has a plug and
outlet as illustrated in Fig. 2. Use only 3-wire exten-
sion cords which have 3-prong grounding type plugs
and 3-pole receptacles which accept the lathe’s plug.
230 volt lathes use a plug and outlet like those illus-
trated in Fig. 3.
Replace or repair damaged or worn cords immedi-
ately.
