2. Replace the installed magnetic switch with the
switch rated for 460V operation (stock no.
PJ1696-205D; separate purchase).
3. Change the dial on the overload relay to the
appropriate setting for 460V operation.
4. Check for proper direction of rotation
(cutterhead should rotate toward infeed table).
If rotation is in the wrong direction, disconnect
machine and switch any two of the hot leads.
Reconnect power and confirm proper rotation.

Tools required
17mm/19mm wrench
Drive Belt
Remove the three crown nuts and washers (A,
Figure 10) on the belt cover with a 17mm wrench,
and remove the cover. Use a 19mm wrench to
adjust the nuts in the motor support (B, Figure 11).
Raise or lower motor support to obtain proper
tension, then re-tighten nuts.
NOTE: Proper tension will be achieved when there
is a small amount of deflection in the belt when
using moderate finger pressure. See Figure 12.

Replacing Knife Inserts
The cutterhead on the PJ1696 is a solid steel
helical insert design with 56 two-sided standard
knives, and two rabbet knives on the outboard end
of the cutterhead. Replacing knives is a simple
process, and they will seat themselves properly
without having to be set with a knife gauge.
After a period of use, dull knives should be flipped
over, replaced or re-ground. To change a knife:
1. Loosen the gib screw (C, Figure 13) and
remove the knife (D, Figure 13) from the slot.
2. Flip the knife 180 degrees and re-insert it, then
tighten the gib screw (C, Figure 13). To ensure
optimal cutting, all knives in the cutterhead
should be flipped at the same time.
Tighten gib screws firmly.
Loose gib screws can result in knives being
thrown out of the cutterhead, causing severe
damage to the machine and possible serious or
fatal injury to the operator or bystanders.

Setting Outfeed Table
For accurate work in most jointing operations, the
outfeed table must be exactly level with the knives
at their highest point of revolution.
1. Raise the outfeed table to its highest point,
and place a straight edge across it.
