FOOTKITS (MIIIFS & MIIIFN)
Both the MIIIFS and MIIIFN tools come supplied with an additional Flooring Foot that can be fitted to offer extra
stability when the tool is in use.
Fitting Instructions:
1. Remove the flat head cap screws (Fig. 9a) and plastic spacer (Fig. 9b) located on the underside of the tool.
Note (MIIIFN Only): also remove the 2 front pads (Fig. 9c).
2. Install the pre-finished flooring foot and the proper number of shims (Fig. 10A) as follows:
Shims Recommended:
Flooring Thickness
1/2" (12.7mm)*
MIIIFN 2
MIIIFS 1
NOTE: FLOORING PRODUCTS WILL VARY AND THE USER MUST INSURE THE THE TOOL IS SHIMMED PROPERLY
ACCORDING TO THE FLOORING PRODUCT BEING INSTALLED. ONCE PROPERLY SHIMMED, ONLY THE FOOT
WILL CONTACT THE FLOORING.
3. Re-install the flat head screws.
4. Roller adjustment (Fig 11): the tool is shipped with rollers set-up for 5/8"- 3/4" (Fig. 11a) range flooring. For
1/2"- 9/16" range flooring remove o-rings, shafts, rollers and re-install rollers in upper holes (Fig. 11b).
Note: If desired or if proper range of adjustment cannot be achieved, foot may be used without rollers.
FLOORING FOOT INSTRUCTIONS
1. Be sure the foot is flush to the flooring (Fig. 12a). Use the window to verify this (Fig. 12b).
Important: DO NOT STRIKE PRE-FINISHED FLOORING (Fig. 12c)
2. Strike both sides of the foot to set the flooring (Fig. 13a).
3. Actuate the tool after flooring is set (Fig. 13b) and then roll the tool to the next fastener position
CORRECT FASTENER PLACEMENT
When the tool is properly shimmed and with the correct air pressure, the fasteners should be set into the flooring
tongue. (Figs. 14A,B,C). However, some adjustment may be required to ensure the correct drive depth as follows:

• Air pressure too low.
• Fastener above tongue.
• Increase air pressure.
Important: Always test on a scrap piece of flooring first.
* 1/2" Flooring: remove the bumper spacer (p/n
