the throttle into the start position. When starting
the engine, place the product onto the ground in
a flat clear area and hold it firmly in place so as
to ensure that neither the cutting part nor the
throttle come into contact with any obstacle
when the engine starts.
IMPORTANT
5. For safe operation
Never place the throttle into the high speed
position when starting the engine.
3. After starting the engine, check to make sure
that the cutting attachment stops rotating when
the throttle is moved fully back to its original
position. If it continues to rotate even after the
throttle has been moved fully back, turn off the
engine and take the unit to your authorized Red
Max servicing dealer for repair.
USING THE PRODUCT
Cut only materials recommended by the
manufacturer. And use only for tasks explained
in the manual.
1. Grip the handles firmly with both hands using
your whole hand. Place your feet slightly apart
(slightly further apart than the width of your
shoulders) so that your weight is distributed
evenly across both legs, and always be sure to
maintain a steady, even posture while working.
2. Maintain the speed of the engine at the level
required to perform cutting work, and never raise
the speed of the engine above the level
necessary.
3. If the unit start to shake or vibrate, turn off the

HANDLING FUEL
1. The engine of the RedMax product is designed
to run on a mixed fuel which contains highly
flammable gasoline. Never store cans of fuel or
refill the tank of the unit in any place where there
is a boiler, stove, wood fire, electrical sparks,
welding sparks, or any other source of heat or
fire which might ignite the fuel.
2. Never smoke while operating the unit or refilling
its fuel tank.
3. When refilling the tank, always turn off the
engine and allow it to cool down. Take a careful
look around to make sure that there are no
sparks or open flames anywhere nearby before
refueling.
4. Wipe spilled fuel completely using a dry rag if
any fuel spillage occurs during refueling.
5. After refueling, screw the fuel cap back tightly
onto the fuel tank and then carry the unit to a
spot 10feet (3m) or more away from where it
was refueled before turning on the engine.
TRANSPORTATION
1. When hand-carrying the product, cover over the
cutting part if necessary, lift up the product and
carry it paying attention to the blade.
2. Never transport the product over rough roads
over long distances by vehicle without removing
all fuel from the fuel tank. If doing so, fuel might
leak from the tank during transport.

Gasoline is very flammable. Avoid smoking
or bringing any flame or sparks near fuel.
Make sure to stop the engine and allow it
cool before refueling the unit. Select outdoor
bare ground for fueling and move at least
3m(10ft) away from the fueling point before
starting the engine.
The RedMax engines are lubricated by oil
specially formulated for air-cooled 2-cycle
gasoline engine use. If RedMax oil is not
available, use an anti-oxidant added quality oil
expressly labeled for air-cooled 2-cycle engine
use. (JASO FC GRADE OIL or ISO EGC
GRADE)
RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
Exhaust emission are controlled by the
fundamental engine parameters and
components(eq., carburation, ignition timing
and port timing) without addition of any
major hardware or the introduction of an
inert material during combustion.
These engines are certified to operate on
unleaded gasoline.
Make sure to use gasoline with a minimum
octane number of 90 ROZ(USA/Canada : pump
octane min.87)
Unleaded gasoline is recommended to reduce
the contamination of the air for the sake of your
health and the environment.
Poor quality gasolines or oils may damage
sealing rings, fuel lines or fuel tank of the
engine.
HOW TO MIX FUEL
1. Measure out the quantities of gasoline and oil to
be mixed.
2. Put some of the gasoline into a clean, approved
fuel container.
3. Pour in all of the oil and agitate well.
4. Pour in the rest of gasoline and agitate again for
at least one minute.
5. Put a clear indication on the outside of the

HEDGE TRIMMING TECHNIQUES
Trim sides of a hedge first, and then the top.
Vertical cut:
With the single-sided blade hedge-trimmer,
model HTZ2500 always cut from the bottom up
(OP9). With the 2-sided blade model CHTZ2500
use an arcing cut from the bottom upwards, then
downwards to use both sides of the blades
(OP10).
Horizontal cut:
In order to get the best cutting results, slightly tilt
the blade (5÷10°) towards the cutting direction
(OP11, OP12).
Cut slowly, specially with thick hedges.
Always follow the safety precautions.
The hedge-trimmer must only be used to trim
hedges or small bushes. It is forbidden to cut
other types of material. Do not use the hedge-
trimmer as a lever to lift, move or break objects,
nor lock it on fixed supports. It is forbidden to
apply tools or applications that are not the
ones indicated by the manufacturer onto the
hedge-trimmer’s power take-off. Do not use it
for pruning trees or cutting grass.
