BISCUIT JOINER SAFETY WARNINGS

BISCUIT JOINER SAFETY

1. TOOL PURPOSE

This biscuit joiner is designed to create appropriately 

sized slots in wood to allow easy joining with biscuits.  

Using the machine for any other purpose for which 

it is not designed may result in serious injuries, 

machine damage, and voiding of the warranty.

2. PERSONAL SAFETY.

• Always wear ANSI Z87.1-approved glasses with 

side shields, hearing protection and a dust mask.

• DO NOT wear loose clothing or jewelry, as they 

might get drawn in by the tool. Tie back long hair.

• DO NOT wear gloves while operating this machine.

3. ELECTRIC CORDS.

Keep cords away from heat, oil, sharp edges, and 

moving parts of the tool. Have an electrician replace 

or repair damaged or worn cords immediately.

4. TOOL INSPECTION.

Before operation, check the tool for any damaged 

or missing parts. Do not use the tool if any part 

is missing or damaged. Do not use the tool if the 

power switch is faulty, the plug or cable is damaged, 

or the tool produces sparks, smoke, or unpleasant 

odors (you may smell brushes wearing down for a 

few minutes as the tool breaks in during the first 

use, that is normal). Make sure all adjustments are 

correct and all connections are tight.

5. SECURING THE WORKPIECE.

Use clamps to secure the workpiece whenever 

possible to prevent wobble, damage to the workpiece, 

and personal injury. Never hold a piece being cut 

in your hands or across your legs. It is important 

to support the work properly to minimize body 

exposure, blade binding, or loss of control.

6. STANDING POSITION.

Make sure to stand in a stable and sturdy stance with 

a tight grip on the joiner. Kickback could cause the 

joiner to jump when in use.

7. STARTING THE TOOL.

Always start the joiner before the blade is in contact 

with the workpiece. Let the blade reach full speed 

before using the tool. The reaction to the torque as 

the motor accelerates to full speed may cause the 

tool to kick back.

8. KEEP HANDS AWAY. Keep hands away from the 

cutting area and the blade. Do not reach underneath 

the workpiece. The blade guard cannot protect you 

from the blade protruding from the underside of the 

workpiece. Do not attempt to remove cut material 

when the blade is moving.

9. DURING OPERATION.

Do not apply excessive pressure to the tool. 

Overstressing the tool may cause kickback and 

damage the tool and accessories. Use special care 

when working corners, sharp edges etc.

10. TURNING OFF THE TOOL.

The blade coasts after the joiner is turned off. Wait 

until the blade comes to a full stop before reaching 

for loose materials or setting the tool down.

11. REPLACING THE JOINER BLADE.

Check the blade for chipped or broken teeth. Do not 

use dull or damaged blades. Unshaped or improperly 

set blades produce narrow kerf, causing excessive 

friction, blade binding, and kickback. Always use 

blades with correct size and arbor holes. Blades that 

do not match the mounting hardware of the joiner 

will run eccentrically, causing a loss of control.

13. MAKING ADJUSTMENTS.

Always turn off and unplug the joiner before making 

adjustments or changing attachments. Accidental 

start-ups may occur if the saw is plugged in during an 

accessory change. Develop a periodic maintenance 

schedule for your tool. Always make sure the power 

switch is in the OFF position and the machine is 

unplugged when doing any cleaning, assembly, 

setup operations, or when not in use.

WARNING!

 Do not let comfort or familiarity with the product replace strict adherence to product safety rules. 

Failure to follow the safety instructions may result in serious personal injury.
