  Prior to using the machine, remove nails that may be present in the floor.  Pre-slitting 

carpet with a knife or a Crain No. 265 Stand-Up Cutter helps the machine remove 
the material with less effort.  

  Peel back an edge of the material to be stripped.  A scraper (Crain No. 390) or a 

pulling claw (Crain No. 844) in the case of carpet can be helpful. 

  Check that the blade is fastened properly and that the blade screws, and extendable 

handle T-bolts are tightened securely.  Remove all wrenches or other tools attached 
to the machine prior to starting.

  Grip machine at the vinyl grips of the extendable handle which provide electrical 

insulation.  Rubber gloves and rubber soled boots provide additional insulation.

  Turn on the machine by depressing the green button 

(Figure 10), and push the blade into the exposed edge 
of the flooring to be stripped.  It is best to push the 
machine gradually and not to ram it into the material. 
Ramming can damage the internal mechanisms and 
void the warranty.

  Do not force the machine.  The machine works best moving forward at a controlled pace.

  Keep blades sharp.  Machine performance depends on sharpness of blades.

  Keep clear from the sharp blade at all times.  Keep feet and hands out from under 

the machine.

  To stop the machine, back it away a short distance to disengage the blade from 

the flooring being stripped.  Press the red button to turn off power to the machine 
(Figure 10).  The machine will come to a stop shortly after it is turned off.  Do not 
leave the machine running unattended.  Switch off machine after each operation.

BUTTONS

  Switch off and unplug the machine before performing any maintenance.  Keep 

water and other liquids out of the machine particularly the motor, switch, wiring, 
and cords as this can cause an electrocution hazard.  If the vinyl grips which 
provide electrical insulation are lost or damaged, replace immediately (Part No. 
1375-G).  Keep oil and other liquids off the vinyl grips.  Do not use the machine 
if the switch becomes damaged or non-operational.  Switch damage can cause 
the machine to not switch off.  Do not use the machine if the cord, plug, or other 
wiring is cut or damaged.   Do not use the machine without the protective fan cover 
or bottom cover in place.  Keep dust and debris away from vents and openings.

  If abnormal noise or vibration occurs, switch off and unplug machine and have 

it repaired before further use.  If the machine is dropped, the blade carrier (Part 
No. 1718-12) or blade clamp (Part No. 1718-16) can be bent or damaged.  Do 
not use the machine until these parts have been repaired. 

  Do not use the machine if it is damaged.  Do not attempt to dis-assemble or re-

wire the machine.  Repairs should be performed by factory authorized service 
personnel or an electrician.
