Cockshut 30 - Generator; Combination Light Switch and Generator Control; Starter; Battery

DETAILED DES CRIPTIO N - The operator should examine the wiri ng diagram, Plate
No. C-I0-46, to unders ta nd the electrical system thoroughly.
COMB
INA TION LIGHT SWITCH AND GEN ERATOR CONTROL - As described on
pag e 22, this switch has thr ee positi ons: (a) Full In- Low Rate Charge; (b) Half
Out- High Rate Charg e ; (c) Full Out-Lights on the Gen erator Full Charge, as
indi
cat ed by arrow (l) . The tractor op erator is of necessity responsible for the
corr ect use of the switch. Rememb er that ov ercharging will damage the battery.
STA
RTE R - The starting motor which provides the power to crank the engine thro ugh
a conventional bendix
driv e requires little att ention. except to see that the cables
on the switch
ar e clean and tight, an d tha t the insulation on the wires is not cor-
roded
or damaged. It is a good idea to occasionallv check the three cap screws
holding the
starter to the flywheel cov er to see t hat they are tight. No oiling is
required on the
unit as bushings wit h lifetime lubrication are provided .

Op erating In stru ctions for Cock shutt "30" Tra ctor
GENERATOR - The g enerator provided is of the d ust -proof third brush type, and
in normal conditions
requir es little attention exc ept the addition of 4 or 5
dr ops of S.A.E. 20 or 30 engine oil ev ery 60 hours to the oiler at the front and
at the r ear bearings. When oiling the gen erator it is a good idea to also check the
wiring for loose connection ; and worn insulation. In most cases the third br ush
need not be adjusted to control the
rat e of charge as this can be conveniently done
by means of the combination
light switch and g enerator control. If the gen erator
gives trouble, it is suggested that your local deal er be contacted and he will give
the gen
erator the proper service to restore it to its original condition.
CORRODED
TE RMINALS - During the weekly inspection outlined above. examine the
terminals
for c orro sion. ann if present, wash off with hot wat er which may also be
used for cleaning the top of the batt ery . Be sure to use sufficie nt water to wash all
the corr osion down thr ough the box and to the zr ound . as corrosion, even when
washed
awa y fr om the terminals. is still active and can damage the box badly. Two
to
thr ee times a year remove th e ter minals. wash them as out lined above, then
br ighten them UP with wir e wool, apply a light coat of vaseline and reassemble,
being
sur e to tighten the terminals care fully.

BATTERY - The battery which stores the electrical ene rgy , just as the water tank stores
wat er for a city. does so in a chemical for m. A regul ar routine should be established
for att ending the battery as ther e is no b ett er way to insure. th at it will give you
long trouble-
fr ee service.
To service the
batter y, ta ke off the battery cov er after removing the wing nut
ann the batt ery hold-down clamp.
Once a week
or o fte ner inspect th e wa tel' level ann b ring it three-eighths of an inch
above the plates by adding distilled
or clean soft wat er. Adding more than this
may mean
that when the batt er y is warm the wat er may overflow through the
vents. causing' corrosion. At the sam e time the specific grav ity should be checked
ann if below 1225, the tra ctor should be on erat ed with the light swit ch in the
"Hizh Charg e" position a zr eat er p ortion of the time. and if up to full charg e, 1270
to 1285, th e "Low
Charg e" rat e should be used a gr eat er portion of th e tim e.
In cold weath
er batt eries mav fr eeze if not k ent pr operly charged. A partl y charged
hatt erv will fr eeze at 20· F. above zero while a fully charg ed batt er y will s ta nd 45· to 50·
F. below zero.
The batt ery should also be k ept at a high er rate d uring cold weath er as the demands from
the
start er ar e gr eater.
If the tract or is not being used during cold w eath er the battery should be removed and
left
at your deal er's for prop er attenti on and car e.
