5. Use proper safety clothing and devices when operating the machine (safety gloves, safety
goggles, ear protectors, safety shoes...)
6. Ensure yourself that there are neither water or gas pipes nor electric lines installed under-
ground in the working area.
Ensure yourself that there are no loose objects lying around in the working area
Eliminate high grass, bushes etc. from the immediate working area. They might be winded
up by the rotating drill and block it.
Take especially care, if the ground contains many stones or roots. An unattended stalling of
the drill might easily cause an accident
To reduce the risk of stalling, always drill holes in 2-3 working steps. After each drilling
sequence, pull out the drill and let get it rid of the ground material
7. Refueling
No open light, fire, sparks or smoking allowed in the surrounding of 10m.
Do not refuel when the engine is running and/or engine parts are still hot.
Refuel only outdoors or in well ventilated areas.
Cleanse spilled gasoline immediately.
OPERATION INSTRUCTIONS
IMPORTANT: The first 10 hours of operation the machine shall not be operated but only
at medium engine speed. Do not operate the engine at max. speed right from the start,
as the engine itself as well as the gearing components need a running-in time. The
engine itself reaches its max. capacity after the first 10 hours of operation. Non-compli-
ance with this instruction reduces your engine lifespan substantially. To reduce the
max. possible engine speed, turn the adjustment knob (h-5), so that the throttle
lever(h-4)cannot be pushed entirely in.
1. Refueling
The machine is run by a gasoline-oil mixture. You need for the 2-stroke engine a fuel mixture
of 30: 1
Ensure yourself that no particles get into the fuel tank when refueling. Use a filter. We
strongly recommend the usage of HQ premixed fuels especially recommended for 2-stroke
motors. Many of them keep their consistency even after long periods of storage. If you prefer
to mix your own fuel please use HQ Synthetic Oil for 2-stroke engines. Synthetic oil reduces
accumulation of soot on the spark plug, cylinder, engine cock and exhaust pipe. This
increases the degree of lubrication and prolongs the engines lifespan.
Note: Shake fuel tank prior to every usage! During storage oil descents slowly in the fuel
tank. If you start the engine under this condition, it has barely any lubrication which would
lead to severe engine damage.
2. Cold starting
● Put the choker into position as shown in(Fig. C) ● Put the switch (H-3)into position START.
● Operate the fuel pump (I-9)3-5 times(Fig. k)
● Press the security lever(H-1)with the heel of your hand. ● Operate the throttle lever(h-4)
● Push the locking lever(h-2)in order to block the throttle lever.
● Now grasp the starter handle(1-4)and pull it out briskly! Repeat if necessary.
● After the engine has started, release the locking lever(h-2).
● Let the engine run in idle speed for 2-3 Minutes
● Put the choker into position as shown in(Fig. D).
3. Warm starting
● Put the switch(h-3)into position START. ● Operate the fuel pump(1-9)3-5 times(Fig. K).
● Press the security lever(h-1) with the heel of your hand.
● Operate the throttle lever(h-4)Push the locking lever(h-2)in order to block the throttle ever.
● Now grasp the starter handle(1-4)and pull it out briskly! Repeat if necessary.
● After the engine has started, release the locking lever(h-2)
Shut the machine off by releasing the throttle lever and put the switch(h-3)into STOP position.

MAINTENANCE
ATTENTION - DANGER!
No cleaning, upkeep, checks or maintenance when machine is running
Be safe: Shut off the machine, let it cool down, disconnect spark plug cap from spark
Plug.
The machine does not require intense maintenance. However, to ensure a long lifespan,
we strongly recommend following the upkeep and maintenance plan.
1. Upkeep and maintenance plan
2. Cleaning
Clean the machine from soil, dirt, grass etc. Clean the machine housing with a wet cloth and a
mild cleaning solution.
IMPORTANT
The usage of solvents, aggressive chemicals or scouring agents damages the machine
solution.
3. Clean the spark plug
Take off the spark plug cap (I-2). Loosen and remove the spark plug. Clean it with a small
brush from soot debris. The contact distance shall account approx. 0, 5mm or credit card
thickness.
4. Grease the gear box
Grease every 25 operation hours the gearing of the earth auger with a grease gun. Use for
this purpose commercial HQ gearing grease.
You will find the lubrication nipple (Fig. J) on the side of the gearbox.
5. Clean the air filter
A clogged air filter reduces the engines power output drastically and causes engine
dis-function.
Furthermore it reduces the engines lifespan!
Loosen with a hex-key the screw fixing the air filter cover (Fig. E).
Take off the cover and remove the filter (Fig. F).
Clean the air filter (Fig G) with water. Wring it out strongly. Let it dry. Drip some drops of oil
onto the filter. Mount the filter back and mount on the cover again.
6. Disposal
DO NOT dispose your earth auger in the residual waste! Contact your local authorities for
information about best available disposal possibilities in your area. Drain fuel from the fuel
tank completely before disposing the earth
auger. Disaggregate the auger into its components before disposing its components.
7. Storage
When you store the machine longer than 30 days:
● Drain fuel from fuel tank
● Remove the spark plug, pour into the cylinder some drops of motor oil. Now pull the starter
cable out slowly so that the engine revolutes several
times in order to distribute the oil in the whole
combustion chamber
● Clean the spark plug as described in 1.6.3 and
mount it back.
● Cover the machine with a cloth sheet and store
it at a dry place.
