G8689 Mini Mill (Mfg. 8/06+)

Additional Safety Instructions for Mini Mill

No list of safety guidelines can be complete. 

Every shop environment is different. Always 

consider safety first, as it applies to your 

individual working conditions. Use this and 

other machinery with caution and respect. 

Failure to do so could result in serious per-

sonal injury, damage to equipment, or poor 

work results.

Like all machines there is danger associ-

ated with the Model G8689. Accidents are 

frequently caused by lack of familiarity or 

failure to pay attention. Use this machine 

with respect and caution to lessen the pos-

sibility of operator injury. If normal safety 

precautions are overlooked or ignored, seri-

ous personal injury may occur.

1.

 

UNDERSTANDING CONTROLS.

 

Make 

sure you understand the use and operation 
of all controls.

2.  SAFETY ACCESSORIES.  Always  use  the 

chip guard in addition to your safety glasses 
when milling to prevent bodily injury.

3.  WORK HOLDING. Before  starting  the 

machine, be certain the workpiece has been 
properly clamped to the table. NEVER  hold   
the workpiece by hand when using the mill.

4.  CHUCK KEY SAFETY

Always  remove 

your  chuck  key,  drawbar  wrench,  and  any 
service tools immediately after use.

5.  SPINDLE SPEEDS.  Select  the  spindle 

speed

  which  is  appropriate  for  the  type  of 

work and material. Allow the mill to gain its 
full speed before beginning a cut.

6.  POWER DISRUPTION. In  the  event  of  a 

local  power  outage  during  use  of  the  mill, 
turn 

OFF all switches to avoid possible sud-

den start up once power is restored.

7.  SPINDLE DIRECTION CHANGES. Never 

reverse  motor  direction  while  the  mill  is  in 
motion.

8.  STOPPING SPINDLE.  DO  NOT  stop  the 

mill using your hand against the chuck.

9.  BE ATTENTIVE.  DO  NOT  leave  mill  run-

ning unattended for any reason.

 

10.  MACHINE CARE AND MAINTENANCE. 

Never  operate  the  mill  with  damaged  or 
worn  parts.  Maintain  your  mill  in  proper 
working  condition.  Perform  routine  inspec-
tions  and  maintenance  promptly.  Put  away 
adjustment tools after use.

11.  DISCONNECT POWER. Make sure the mill 

is turned 

OFF, disconnected from its power 

source  and  all  moving  parts  have  come  to 
a complete stop before starting any inspec-
tion,  adjustment,  or  maintenance  proce-
dure.

12.  AVOIDING ENTANGLEMENT. Keep loose 

clothing  articles  such  as  sleeves,  belts  or 
jewelry items away from the mill spindle.

13. TOOL HOLDING. Always  use  the  proper 

tools

 for the material you are milling. Make 

sure  they  are  held  firmly  in  the  proper  tool 
holder for the job.

14. CLEAN-UP. DO NOT clear chips by hand. 

Use a brush, and never clear chips while the 
mill is turning.

15.  CUTTING TOOL INSPECTION.

 

Inspect 

drills  and  end  mills  for  sharpness,  chips, 
or  cracks  before  each  use.  Replace  dull, 
chipped,  or  cracked  cutting  tools  immedi-
ately.  Handle  new  cutting  tools  with  care. 
Leading  edges  are  very  sharp  and  can 
cause lacerations.
