Basic Tool Use and Safety

basic tool use and safety

general shop rules
All tools must be put away before closing the lab at the end of a working session.
Put away all tools upon completion of a task.
Non-design tasks should be kept to the lower half of the barn.
Don’t use the floor as a temporary or long-term work surface.
Clean up metal shavings and small scrap using the shop vacuum and broom.
Always wear appropriate safety gear.
Finish your project or ask for assistance before moving on to another.
Avoid being idle and always be on the look out for tasks to do.

die grinder
The die grinder is used for small grinding applications.
The grinder must be hooked up to the pneumatics system for use.
The bit may be changed depending on the application.
The grinder accepts different sized collets corresponding to the different shanks of the grinding bits.
While grinding, wear the full face mask and respirator.

cut-off tool
While using the cut-off tool, wear the full face mask and respirator.
The cut-off tool must be hooked up to the pneumatics system for use.
Hold the tool so that the clear plastic shield faces you.
Use the tool to make straight cuts only.
Hold the tool with two hands while cutting.
Don't apply excessive pressure when cutting, as the blade may break.

impact wrench
The impact wrench is used to securely tighten a nut.
The impact wrench must be hooked up to the pneumatics system for use.
The wrench accepts 3/8" sockets.
Toggle the direction with the switch located on the handle.

angle grinder
A grinding disc is damaged and unusable if:
Cracks are visible
The disc is irregularly shaped near the outer edge.
Grind with foremost part of disc and away from the central hub.
While grinding, wear the full face mask and respirator.
While grinding, hold the tool with two hands.
Set down and store the angle grinder with the disc positioned downwards.
Allow the disc to spin to a stop before setting down the tool.
The button on top locks the grinder so that the blade may be changed.
Do not lock the grinder while the disc is spinning

reciprocating saw
Use the reciprocating saw for rough cuts only.
Use any fine toothed blade when cutting metal.
Use any coarse toothed blade when cutting plastic or wood.
Use a hex wrench to loosen and tighten the blade.
Adjust the saw speed using the dial on top of the saw.
Lock and unlock the tool’s trigger with a button on the side of the tool.
Position the rocking guide against the work piece to steady the tool.
Hold the tool with one hand forward and one hand positioned on the handle.

circular saw
Clamp down the work piece.
Be cautious that the blade beneath the cutting plane does not make contact with either yourself, the ground, or any blocks used.
Hold the saw with two hands
Don't force the saw into the work piece. Instead, allow the saw to pull itself along
How to adjust the saw’s cutting angle and depth:
Angle: Use the lever on the front of the saw.
Depth: Use the lever near the back of the saw to set and lock the cutting guide.
Check that the appropriate blade is installed before cutting.
Sometimes it is necessary to lift the blade guard to begin the cut.

chop saw
Clamp down the work piece.
The clamps can be positioned on either side of the cutting blade.
Check that the appropriate blade is installed.
Allow the blade to spin up before beginning to cut.
Lower the blade slowly to avoid jams.
In case of a jam, release trigger and raise the blade before restarting the cut.

band saw
Don't apply pressure to the cutting arm.
Set the spring for an appropriate cutting pressure.
Set the blade opening to the smallest possible distance.
Use the vice set to the desired correct angle to secure the work piece.
Start the saw before the blade makes contact with the work piece.
If the blade does not start to move, turn off the saw, spin the blade by hand, and then restart the saw.
To convert to a vertical saw:
Put the saw arm in the vertical position
Screw on the table
Ask for assistance if the blade falls off.

drill press
Drilling speed can be adjusted by changing the belts at the top of the drill press.
Use the chuck and chuck key to vary the space for the desired bit.
Be sure the chuck key is removed prior to turning on the drill press.
When drilling a large hole, begin by drilling a smaller pilot hole and gradually working up to the desired final size.
Be sure not to allow the spinning drill bit to touch and damage the table.
