THICKNESS PLANER SAFETY

1
THICKNESS PLANER SAFETY
2
SPECIFIC PURPOSE

• To surface stock to desired thickness.

3
SPECIFIC SAFETY RULES

• Stock must be at least 12 long to go through the
  GENERAL planer and at least 8 long to go through
  the DeWALT planers.
• Plane thickest board first. Never plane more than
  one thickness at a time.

4
Specific Safety Cont

• Never stand directly behind, always off to one
  side in case of kick back.
• Let go of the stock the board after it starts
  through the planer.
• Never look into the planer.

5
USEFULL TIPS

• Measure the thickness of your stock and adjust
  the planer to remove 1/16 of material thickness.
• The JOINTED or SMOOTH face of your stock must be
  facing DOWN when you plane for the first time.
• Rotate the hand wheel on the side of the planer
  by 1/3 of a turn to reduce stock thickness until
  proper thickness is achieved.

6
Useful Tips Cont

• When planing short pieces (ie. 16 to 12) put
  the pieces through end to end so they push each
  other through the planer.
• Plane all your stock at the same time to ensure
  equal thickness.
• Ask for a help when planing long boards.
• Check your stock for nails and loose knots.

7
Why is a thickness planer not able to straighten
a warped board?

• BECAUSE..
• The Cutterhead is mounted above the table.
• Only the top of the stock is surfaced.

8
Briefly explain how FEED SPEED affects surface
finish?

• Faster feed fewer knife marks/inch
• rougher surface quality
• Slower feed more knife marks /inch
• smoother surface quality
