10 x 16" TYPE TS-2 HAND SURFACE GRINDER

Initial Setting Up

On Receipt of Machine

Your 10 x 16" Type TS-2 Hand Surface Grinder is built to
provide precise service, and must be handled as a precision tool.
Remove the packing materials with care.

Avoid direct, heavy blows on these materials to prevent

shocks to the machine,

In removing blocking, see that this is done so

as to avoid undue stresses on machine or its components.

Separately Packed Material

Certain machine components are packed separately.

Handwheels

If the handwheels are received separately, their identifica
tion and proper location should be no problem. The wheel feed hand-
wheel is shown as #10TS-24 on the Vertical Slide Feed Mechanism
drawing. The table drive handwheel is shown as #72 on the Cross Slide

Assembly drawing. The cross-feed handwheel is shown as #55.

The drawings also indicate how the handwheels are mounted.
In mounting table drive handwheel #72, it will be seen that this can be
oriented (because of the serrated washer #73) to bring handle #56 into
any position desired by the Operator. This is particularly helpful if
much short-table-stroke grinding is to be done, and the Operator finds
it easier to have the handle #56 in a certain position.
