WARNING  
NOTE  
• 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 10 ft (3 m) away from  
the fueling point before starting the engine.  
• Failures caused by operating engines on gasoline with octane  
rating lower than 89 are not covered by the RedMax Two-  
Stroke engine warranty.  
WARNING  
• Alternative Fuels (Not Gasoline)  
Alternative fuels, such as E-15 (15% ethanol), E-20 (20%  
ethanol), E-85 (85% ethanol) are NOT classified as gasoline  
and are NOT approved for use in RedMax 2-stroke gasoline  
engines. Use of alternative fuels will cause major engine  
performance and durability problems such as: improper  
clutch engagements, overheating, vapor lock, power loss,  
lubrication deficiency, deterioration of fuel lines, gaskets  
and internal carburetor components, etc... Alternative fuels  
cause high moisture absorption into the fuel/oil mixture  
leading to oil and fuel separation.  
GASOLINE REQUIREMENTS  
• All 2-Stroke RedMax Products are powered by RedMax  
Professional-Commercial Duty, Hi-Performance, Hi-RPM, Air  
Cooled 2-Stroke engines.  
RedMax – Hi-Performance 2-stroke engines produce higher HP  
outputs as compared to standard Home Owner Duty or Light  
Commercial Duty production engines offered by most  
manufacturers.  
• 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.  
• The RedMax Engines are registered and certified with CARB  
(California Air Resources Board) and EPA (Environmental  
Protection Agency) to operate on CLEAN Mid-grade 89 octane  
or Premium, unleaded (lead-free) gasoline and RedMax Air-  
Cooled "Max Life", Synthetic blend Premium two-stroke engine  
oil mixed at 50:1 ratio.  
OIL REQUIREMENTS  
• Use only RedMax "Max Life", Synthetic blend Premium Air-  
Cooled two-stroke engine oil or oil certified to ISO-L-EGD  
(ISO/CD1378) standard AND one that is JASO-FD registered.  
RedMax Air-Cooled "Max Life", Synthetic blend Premium two  
stroke engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-FD  
oils are fully compatible with gasoline's containing 10% Ethanol.  
RedMax Air-Cooled "Max Life", Synthetic blend Premium two  
stroke engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-FD  
oils are Universal and should be mixed at 50:1 ratio for all 2  
stroke air cooled engines sold in the past regardless of mixing  
ratios specified in those manuals.  
• Unleaded gasoline is recommended to reduce the  
contamination of the air for the sake of your health and the  
environment.  
• If the oil is registered with JASO, the JASO Logo with FD and  
registration number will be displayed on the container. The  
highest JASO rating is "FD", which equals the ISO-L-EGD  
rating. Lower ratings are "FC", "FB", and "FA".  
• This Hi-Performance Air Cooled 2-stroke Engine requires the  
[ R+M ]  
use of Minimum 89 Octane  
(Mid grade or Premium)  
2
clean gasoline. Gasoline may contain maximum of 10% Ethanol  
(grain alcohol) or up to 15% MTBE (Methyl tertiary-butyl ether).  
Gasoline containing Methanol (Wood Alcohol) is NOT  
approved.  
NOTE  
• Engine problems due to inadequate lubrication caused by  
failure to use ISO-L-EGD certified and JASO FD registered oil  
such as "MaxLife", RedMax Synthetic blend Premium 2-stroke  
oil WILL VOID THE REDMAX TWO-STROKE ENGINE  
WARRANTY.  
• IF octane rating of the Mid Grade gasoline in your area is lower  
than 89 Octane use Premium Unleaded Gasoline. The majority  
of all 2-stroke engine manufacturers in the USA and Canada  
recommend using gasoline with 89 Octane or higher.  
WARNING  
WARNING  
• Gasoline with an octane rating lower than 89 will greatly  
increase the engines operating temperature. Low octane  
gasoline will cause detonation (knock) resulting in piston  
seizures and major internal engine components damage.  
• Poor quality gasolines or oils may damage sealing rings, fuel  
• Do not use NMMA (National Marine Manufacturers  
Association), BIA (Boating Industry Association), and TCW (two  
cycle water cooled) oils designed for MoPeds or Outboard,  
water cooled Marine Engines. Do not use API (American  
Petroleum Institute), TC (Two Cycle) labeled oils. The API-TC

test standard has been discontinued by API in 1995 and it no  
longer exists.  
WARNING  
1. Select flat and bare ground for fueling.  
2. Move at least 10 feet (3 meters) away from the fueling point  
before starting the engine.  
3. Stop the engine before refueling the unit. At that time, be  
sure to sufficiently agitate the mixed gasoline in the  
container.  
IMPORTANT  
U
S
• Gasoline/Oil mixture Storage Recommendations  
Store your gasoline or gasoline/oil mixture in a cool dry area in  
a tightly sealed approved container to limit the entry of moisture  
and additional air (oxygen). Moisture and air cause the  
development of varnish and gum, making the fuel stale. Stored  
gasoline and gasoline/oil mixture ages and loses its octane  
rating and volatility. Do not mix more gasoline/oil than you  
intend to use in 30 days, and 60 days when fuel stabilizer is  
added. RedMax Air-Cooled "Max Life" Synthetic blend  
Premium two-stroke engine oil "Contains fuel stabilizer" and  
will automatically extend your gasoline/oil mixture life up to 60  
days.  
FOR YOUR ENGINE LIFE, AVOID  
1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause severe  
damage to the internal engine parts very quickly.  
2. GASOHOL – It can cause deterioration of rubber and/or plastic  
parts and disruption of engine lubrication.  
3. OIL FOR 4-CYCLE ENGINE USE – It can cause spark plug  
fouling, exhaust port blocking, or piston ring seizure.  
4. Mixed fuels which have been left unused for a period of  
one month or more may clog the carburetor and result in the  
engine failing to operate properly.  
5. In the case of storing the product for a long period of time,  
clean the fuel tank after rendering it empty. Next, Start the  
engine and run the carburetor dry residual fuel.  
6. In the case of scrapping the used mixed oil container, scrap it  
only at an authorized depository site.

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.  
Proceed as follows:  
1. Free the handle by pressing the locking  
lever; (OP7)  
2. Turn the handle until the locking lever  
clicks into place;  
3. When the handle is locked in its new  
position, you can apply the throttle  
again.  
OP8  
OP12  
(1) handle  
(2) locking lever  
• Use only as much throttle as is needed  
to do the job. Excessive engine speed  
is unnecessary.  
• Avoid cutting thick branches, for which  
will damage the blades and shorten the  
life of drive systems.  
You can swivel the handle even with the  
engine idling because the hedge-trimmer  
is equipped with a blade brake that  
maintains the blades at a standstill.  
• Always keep your body to the  
carburetor side of your trimmer, never  
on the muffler side.  
• When a new machine is first operated,  
in the first few minutes grease may  
come out of the gear case. But, since  
this is excess grease, there is no cause  
for alarm. Just wipe it off with the  
engine stopped for next use.  
HEDGE TRIMMING TECHNIQUES  
Trim sides of a hedge first, and then the  
top.  
OP9  
Vertical cut:  
• With the single-sided blade hedge-  
trimmer, model HTZ2460/HTZ2460L  
always cut from the bottom up (OP9).  
• Always remember that the TIP of the  
line does cutting. You will achieve  
better results by not crowding the line  
into the cutting area. Allow the unit to  
trim at its own pace.  
OP10  
• With the 2-sided blade model  
CHTZ2460/CHTZ2460L use an arcing  
cut from the bottom upwards, then  
downwards to use both sides of the  
blades (OP10).

PROCEDURES TO BE PERFORMED  
AFTER EVERY 100 HOURS OF USE  
1. Remove the muffler, insert a  
MA11  
screwdriver into the vent, and wipe  
away any carbon buildup. Wipe away  
any carbon buildup on the muffler  
exhaust vent and cylinder exhaust port  
at the same time.  
2. Tighten all screws, bolts, and fittings.  
3. Check to see if any oil or grease has  
worked its way in between the clutch  
lining and drum, and if it has, wipe it  
away using oil-free, lead-free gasoline.  
MUFFLER  
WARNING  
• Inspect periodically, the muffler for  
loose fasteners, any damage or  
corrosion. If any sign of exhaust  
leakage is found, stop using the  
machine and have it repaired  
immediately.  
• Note that failing to do so may result  
in the engine catching on fire.
