Handheld Circular Saw Introduction

This is the content required for an introduction to our circular saws - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)

Let's begin! First off, make sure you have read the machine's manual:

• Herkules BHK 1600LE "Laser Beam"
• Festool TS 75 EBQ (plunge saw)

Safety

Dangers

• sawdust and small splinters can fly towards the operator and others
• sharp and rotating exposed blade - will keep spinning for a bit after turning the power off!
• kickback: if the blade binds with the material it can push the saw back towards the user - this happens usually, when the blade is pinched. Example video: https://youtu.be/OdW7vhYYSdM?t=95

Precautions

general:

• hook up a shop vac, but be aware the dust extraction from our "Herkules" saw is very incomplete
• wear goggles and ear defenders!
• dust mask: depending on the material you're cutting
• get a helper who can hold your cutoff (depending on the size it) so it doesn't fall down
• make sure the cutting path is free of obstacles (except your workpiece of course)
• let the saw start before touching the workpiece
• keep the saw secure after your cut until is has come to a complete stop

plunge saw (Festool TS 75):

• when doing a plunge cut make sure the rail/workpiece can't move sideways. This could cause the blade to bind and kickback.
  • attach the endstop to the rail to reduce the chance of kickback
• use an appropriately sized riving knife (DE: Spaltkeil) when using a different blade
  • remove the riving knife for plunge cuts, otherwise it can get in the way

Demonstration

The tutor will show you these steps in detail:

• using the proper circular saw guide

Festool TS 75:

• change cutting angle
• change and lock cutting depth
