Kenwood Chef A.700 Service Manual

'CHEF' MODEL .:.700 & A.700D
INTRODUCTION
MODEL A.700
lhe Kenwood "Chef" Model A.700 consists of a cast
aluminium body, designed to house the Motor and Gears.
Provision is made for the body to hinge backwards and a
spring-loaded catch allows it to be locked in ihe tilted
position.
ihe Mixing Bowl is secured by the location of bayonet slots
with lugs on the Pedestal.
Mounted vertically in the Body is a series wound universal
motor fitted with a variable speed control. The end of the
motor shaft is fitted with a drive pin that engages with a slot
in the shank of a spring-loaded Pinion Gear.
Along the top of the Body a train of three-reduction gears
is arranged.
The gear housing is grease packed and is enclosed by a top
cover which also forms a handle.
A removable Cover Cap encloses the motor output shaft while
the Juice Extractor socket is peed by a chromium-plated
screw-in plug. The outlet socket at the nose end has a plastic
cap held in position by a clamp screw. This screw also holds
the various attachments in position. The Top Cover and Body
are sealed by a rubber jointing ring, located in a groove
around the Body flange.
When the Liquidiser Goblet base is placed in position over
the end of the Motor Spindle, the motor drive is disengaged
from the pinion and gear train by a decoupling plate which
presses down on the rim of the motor drive pinion.
Orbit movement of the rotating beater is obtained through the
Planet Hub. An off centre output socket retains the plug-in
Beater, Whisk and Dough Hook Attachments.
MODEL A.700D
The "Chef" Model A.700D is a Double Insulated Machine
and need not be earthed. A twin-core cable is, therefore, fitted.
These Machines have many parts in common with the original
"Chef". The basic construction is the same, the main difference
being the Motor and Controller, which have plastic end
frames and Drive Pinions.
Many improvements have been introduced on this model,
namely, improved Motor Oil Seal and Controller Yoke, nylon
Beaker Drive Dog, etc. The layout of Chokes and Resistances
also differs from the A.700.
