When stripping on concrete, install the blade with the bevel up. On wood floors,
or gibcrete or soft poured flooring, install the blade with the bevel down to reduce
unnecessary gouging or sticking of the blade into the floor. On soft wood subfloors
(like particle board), it may be advisable to slightly dull the blades before use.
�
The blade carrier has a number of holes for various blades (Figure 5 - see previous
page 3). See the table above for the proper holes to be used with each blade.
�
For Crain blades with slots, slide the blade under the blade clamp until the blade
slots bottom on the blade screws. (For blades with holes, the blade screws, blade
clamp, and blade must be removed, then install the screws through the blade
holes.) Reassemble the blade clamp, blade and screws on the blade carrier.
�
Tighten the blade clamp firmly with the proper blade screws fastened in the proper
holes prior to starting the machine.

FASTENING BLADES:
Select a blade for the material you are stripping. See the table below for general
guidelines on blade usage. For each blade, the table also lists information about
the proper screw holes to be used on the blade carrier. The screw holes are shown
in Figure 5 (see previous page 3). To install the thin spud blade for tough take-up
jobs, use the two inner holes. For other blades, please reference the table below:

In general, it is advisable to begin with narrower blades to determine the difficulty
of the take-up job. If the material comes up easily, switching to wider blades can
take up wider sections of material. The wide 16" blades are “cleaner blades” mainly
used to remove residual adhesive only after the flooring material has been stripped.
