warmer location. After ice drill has been allowed to warm up
sufficiently, repeat steps 1 – 5.
USING YOUR JIFFY PRO4 ICE DRILL
NOTE: To minimize water splash, back-off throttle when the
drill breaks thru ice, then raise drill slowly.
NOTE: The clutch slips when the drill is overloaded, when this
happens, raise complete unit slightly to ease load.
NOTE: Remove blade protector from drill assembly prior to
drilling. Reinstall when drilling is complete.
NOTE: If drilling additional holes, carry unit in upright
position by handles only, to next location and proceed
with normal starting and operating instructions.
1. When all holes have been drilled, and engine is stopped, lay
unit down, resting on wing handle with engine spark-plug facing
upward. Disconnect drill assembly from powerhead by sliding
E-Z Connect™ Collar down and pulling clevis pin from drill
assembly. Do not remove pin from collar tether. Slip drill
assembly off of engine output shaft, then re-insert clevis into
drill assembly and slide E-Z Connect™ Collar up to cover clevis
pin.
2. Reattach blade protector to drill assembly to prevent damage to
the blade teeth and point.
TRANSPORTING AND STORAGE
1. Disconnect propane tank and remove tank from engine.
2. Always transport and store powerhead with powerhead in
an upright (operating) position or engine spark-plug facing
upward. Make sure powerhead and drill assembly are
properly anchored to prevent damage.

MAINTENANCE AND ADJUSTMENTS

Check SPARK PLUG, periodically.
1. Before removing plug, wipe dirt and debris from spark plug base.
2. Remove and inspect spark plug for carbon build up.
3. Replace spark plug if electrodes are pitted, burned, or porcelain is
cracked. For replacement use: Autolite® 4194 spark-plug or
equivalent. Failure to use proper spark-plug may result in engine
damage.
4. Check spark-plug gap with wire feeler gauge and set gap at .025".
5. Install spark plug in engine and tighten securely.
REPLACEMENT TEETH – Improper cutting may be due to dull or damaged
drill teeth or drill point. Maintain sharp blade teeth and point. Preserve the
original factory cutting angles when sharpening your drill. File blade teeth
and use a disk sander to sharpen the point. Only genuine Jiffy® blade teeth
are to be used.
AIR FILTER – The engine has an air cleaner which helps prevent premature
engine wear and failure. Never run an engine without a complete, clean air
filter properly installed. Clean or replace air filter as
