MOTOR THERMAL OVERLOAD
PROTECTOR
I CAUTION: TO avoid damage, this motor
nr_ot--or
shoued be blown out or vacuumed frequently to
prevent sawdust buildup which will interfere
I with n_ormal motor ventilation,
Your saw _s equipped w_th _ mar'_uaFreset thermal
over_a_ protector designed to open tr_e power line c_r.
cu_ w_en me motor temperature exce6_s a safe teveL
m_or $ overloaded el a low vo_ta_ cona_t_on exls'_.
t. After cooling [o a safe operahng temperature, the
eve#earl protector can be c_es_ manually by push.
{t_g the red button on the end of the motor, if the red
buttO_ W_t not click into place immed_ate{y, the moto_
_ss£!_ too hot and must be allowed] to cool for a while
_onqer.
Th_._brae required for the motor to cooi may be equal
_o _t_e ;ength of time the _3w was useu before t_e
thermal overload protector opened, to shut off eiectri*
ca_ ,'lew. An audible click wilt _nd_cate the pretec[or is
CiOSed
2 As s_,_n as the re4dbutton w_!tdick _nto running posi-
t_ the saw may be started and operated norma!ty,
3 Frequent "b_owing" of fuses or tripping of c_rcu_t
breakers may result if.
a. MOTOR tS OVERLOADED - Overioading can
0ccu[ if yet,; feed too rapidly or if sew is mis_
a_igr_ecL
b MOTOR C_RCL_IT IS FUSED DIFFERENTLY
FROM RECOMMENDATIONS - A!ways fotlow
instructions for the proper fuseibreaker. Do not
use a fusefbreaker of greater capacity without
_msu_ting a qualified electrician.
c, LOW VOLTAGE -Aithough the motor is designed
fo_operation on the voitage and frequency speci-
fied on motor nameplate normal loads wilt be
har_died safely on voltage not more than 10%
above or below the namepiate voltage. Heavy
bads, i_owever, require that voltage a[ motor teF
m,inais equa!s the voltage specified on name
p_ate.
4. Most _otor troubles may be traced to loose or incor-
reel cormect_ons, overloading, reduced input voltage
(such as small size wire in the supply circuit) or to
overly _ong
sup_'31y
circuit wire, Always check the
cofinections the toad and the supply circuit whenev-
er motor fails to perform satisfactorily. Check wire
szes and ler_gthwith the Wire Size Chart below.
W_RE S_ZES
The use of any extension cord Will cause some !oss of
power, To keep this to a minimum and to prevent over-
heating ar_d motor burn-out_ use the table beiow to
determine ti_e minim{Kn wire size (AW, G) extension
co_J Use or_y 3 w_re extension cords which have 3
prong gK._ur_dir]g type plugs and 3_pole receptacles
,,_ff,ich a_ept the toots plug
CAUTION: For circuits that are farther away
from electrical service box, the wire size must
be _ncreased proportionately in order to de_iver
ample voltage tO the saw motor.
