ADJUSTING BLADE HEIGHT

Refer to Figures 12-14.

CAUTION: Make sure the switch is in the OFF posi-

tion and cord is unplugged before proceeding with

checking blades.

The blades have been adjusted at the factory to assure

proper operation and should require no adjustment.

However, shipping and handling may have caused mis-

alignment. For accurate cutting, the blades must be as

high as the outfeed table when positioned at the high-

est point. To check blade height:

• Block the blade guard from closing using a scrap

piece of wood about 61/4"long between the fence

and blade guard.

• Turn the cutterhead so that one of the blades is at

the highest position.

CAUTION: The cutterhead blades are extremely

sharp. Do not let your fingers contact the cutting edge

at any time.

• Place a straightedge over the outfeed table and the

blade.

The straight edge must touch evenly on the outfeed

table at both ends of the blade.

Rotate the cutterhead by hand. The blades should

just touch the straightedge. If a blade is too low or

too high at either end, adjust blade height using the

jack screws.

AVOID DAMAGE TO BLADES

Jointer/planer is a precision woodworking machine and

should only be used on quality lumber. Using bad lum-

ber could result in a poor quality cut on subsequent

pieces.

For proper operation, it is preferable to use the jointer

with a dust collecting system (see Using a Vacuum

Hose, page 9) attached to the exhaust port in the rear

of the jointer. Attaching a dust collecting system is

especially required when taking deeper cuts to prevent

clogging of wood chips.

• Do not use dirty boards. Dirt and stones are abrasive

and will wear blade.

• Remove nails and staples. Jointer should only cut wood.

• Avoid knots. Heavy cross-grain makes knots hard

and they can come loose and jam the jointer.

• Assess value of badly warped boards. Operator can be

tempted to use too deep of cut to square boards quick-

ly. Use several passes to maintain a level surface.

ON-OFF SWITCH

Refer to Figure 15.

The operating positions of the On-Off switch are located

on the front of your jointer/planer.

• Push the switch up to turn jointer/planer on and push

down to turn the unit off.

• The switch has a removable key that allows the unit

to be locked in the OFF position.

To activate locking mechanism:

• Push the switch to OFF position.

• Pull switch key.

To deactivate locking mechanism:

• Insert and press switch key in the slot on switch.

WARNING: Be sure the switch is in OFF position and

the cord is unplugged from the power source before

removing switch key.
