Model G7945/G7946 (Mfd. Since 09/17)

  

WEARING PROPER APPAREL.  Do  not  wear 
clothing,  apparel  or  jewelry  that  can  become 
entangled  in  moving  parts.  Always  tie  back  or 
cover long hair. Wear non-slip footwear to reduce 
risk of slipping and losing control or accidentally 
contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery 
operations  may  cause  cancer,  birth  defects,  or 
long-term  respiratory  damage.  Be  aware  of  dust 
hazards  associated  with  each  workpiece  mate-
rial. Always wear a NIOSH-approved respirator to 
reduce your risk.

HEARING PROTECTION.  Always  wear  hear-
ing  protection  when  operating  or  observing  loud 
machinery.  Extended  exposure  to  this  noise 
without  hearing  protection  can  cause  permanent 
hearing loss.

REMOVE ADJUSTING TOOLS.  Tools  left  on 
machinery  can  become  dangerous  projectiles 
upon startup. Never leave chuck keys, wrenches, 
or  any  other  tools  on  machine.  Always  verify 
removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use 
this  tool  for  its  intended  purpose—do  not  force 
it  or  an  attachment  to  do  a  job  for  which  it  was 
not designed. Never make unapproved modifica-
tions—modifying  tool  or  using  it  differently  than 
intended may result in malfunction or mechanical 
failure that can lead to personal injury or death!

AWKWARD POSITIONS.  Keep  proper  footing 
and balance at all times when operating machine. 
Do not overreach! Avoid awkward hand positions 
that  make  workpiece  control  difficult  or  increase 
the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and 
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce 
accidental  contact  with  moving  parts  or  flying 
debris.  Make  sure  they  are  properly  installed, 
undamaged,  and  working  correctly  BEFORE 
operating machine.

FORCING MACHINERY. Do not force machine. 
It  will  do  the  job  safer  and  better  at  the  rate  for 
which it was designed.

NEVER STAND ON MACHINE.  Serious  injury 
may  occur  if  machine  is  tipped  or  if  the  cutting 
tool is unintentionally contacted. 

STABLE MACHINE. Unexpected movement dur-
ing  operation  greatly  increases  risk  of  injury  or 
loss of control. Before starting, verify machine is 
stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult 
this owner’s manual or the manufacturer for rec-
ommended  accessories.  Using  improper  acces-
sories will increase the risk of serious injury.

UNATTENDED OPERATION. To  reduce  the 
risk  of  accidental  injury,  turn  machine 

OFF  and 

ensure  all  moving  parts  completely  stop  before 
walking  away.  Never  leave  machine  running 
while unattended. 

MAINTAIN WITH CARE. Follow all maintenance 
instructions  and  lubrication  schedules  to  keep 
machine  in  good  working  condition.  A  machine 
that  is  improperly  maintained  could  malfunction,  
leading to serious personal injury or death. 

DAMAGED PARTS.  Regularly  inspect  machine 
for  damaged,  loose,  or  mis-adjusted  parts—or 
any  condition  that  could  affect  safe  operation. 
Immediately  repair/replace  BEFORE  operating 
machine. For your own safety, DO NOT operate 
machine with damaged parts!

MAINTAIN POWER CORDS. When  disconnect-
ing  cord-connected  machines  from  power,  grab 
and pull the plug—NOT the cord. Pulling the cord 
may  damage  the  wires  inside.  Do  not  handle  
cord/plug with wet hands. Avoid cord damage by 
keeping it away from heated surfaces, high traffic 
areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES.  If  at  any  time 
you experience difficulties performing the intend-
ed operation, stop using the machine! Contact our 
Technical Support at (570) 546-9663.
