FUEL	lines or fuel tank of the engine.

WARNING

•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.

■ GASOLINE REQUIREMENTS

• All 2-Stroke RedMax Products are powered by Zenoah Professional-Commercial Duty, Hi-Performance, Hi-RPM, Air Cooled 2-Stroke engines.

RedMax/Zenoah – 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/Zenoah Engines are registered and certified with CARB (California Air Resources Board) and EPA (Environmental Protection Agency) to operate on CLEAN Midgrade 89 octane or Premium, unleaded (lead-free) gasoline and RedMax Air-Cooled "Max Life", Synthetic blend Premium twostroke engine oil mixed at 50:1 ratio.

• Unleaded gasoline is recommended to reduce the contamination of the air for the sake of your health and the environment.

• This Hi-Performance Air Cooled 2-stroke Engine requires the

use of Minimum 89 Octane [ R+M ] (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

•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

•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

US-10

NOTE

•Failures caused by operating engines on gasoline with octane rating lower than 89 are not covered by the RedMax TwoStroke 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.

■ OIL REQUIREMENTS

•Use only RedMax "Max Life", Synthetic blend Premium AirCooled 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.

•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".

•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.

WARNING

•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

7. Fuel

test standard has been discontinued by API in 1995 and it no longer exists.

IMPORTANT

•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.

2.Put some of the gasoline into a clean, approved fuel container.

3.Pour in all of the oil and agitate well for 10seconds.

4.Pour in the rest of gasoline and agitate again for at least one minute. As some oils may be difficult to agitate depending on oil ingredients, sufficient agitation is necessary. Be careful that, if the agitation is insufficient, there is an increased danger of early piston seizure due to abnormally lean mixture.

5.Place a clear indication on the outside of the container to avoid mixing up with gasoline or other containers that dont contain oil.

6.Indicate the contents on outside of container for easy identification.

■ FUELING THE UNIT

1.Untwist and remove the fuel cap. Rest the cap on a clean surface.

2.Put fuel into the fuel tank to 80% of the full capacity.

3.Fasten the fuel cap securely and wipe up any fuel spillage around the unit.

8. Operation

■ STARTING ENGINE

WARNING

The cutting head will start rotating upon the engine starts.

1.Rest the unit on a flat, firm place. Keep the cutting head off the ground and clear of surrounding objects as it will start rotating upon starting of the engine.

NOTE

1.When restarting the engine immediately after stopping it, leave the choke open.

2.Overchoking can make the engine hard to start due to excess fuel. When the engine failed to start after several attempts, open the choke and repeat pulling the rope, or remove the spark plug and dry it.

8. Operation

■CUTTING WORK (LINE HEAD USAGE)

WARNING

1.Always wear eye protection such as safety goggles. Never lean over the rotating cutting head. Rocks or other debris could be thrown into eyes and face and cause serious personal injury.

2.Keep the debris guard in place at all times when the unit is operated.

TRIMMING GRASS AND WEEDS

•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.

OP7

1.Hold the unit so the head is off the ground and is tilted about 20 degrees toward the sweep direction. (OP7)

2.You can avoid thrown debris by sweeping from your left to the right.

3.Use a slow, deliberate action to cut heavy growth. The rate of cutting motion will depend on the material being cut. Heavy growth will require slower action than will light growth.

4.Never swing the unit so hard as you are in danger of losing your balance or control of the unit.

5.Try to control the cutting motion with the hip rather than placing the full workload on the arm and hands.

6.Take precautions to avoid wire, grass and dead, dry, long-stem weeds from wrapping around the head shaft. Such materials can stall the head and cause the clutch to slip, resulting in damage to the clutch system if repeated frequently.

ADJUSTING THE LINE LENGTH

•Your brushcutters is equipped with a semiauto type nylon line head that allows the operator to advance the line without stopping the engine. When the line becomes short, lightly tap the head on the ground while running the engine at full throttle.

•Each time the head is bumped, the line advance about 1 inch(25.4 mm). For better effect, tap the head on bear ground or hard soil. Avoid bumping in thick, tall grass as the engine may stall by overload.

WARNING

•If the grass or other object gets caught in the blade, or if the unit starts to shake or vibrate, turn off the engine and check the whole unit. Change the blade if it has been damaged.

•Turn off the engine and make sure the blade has completely stop before checking the blade, and removing any object got caught in.

■ OPERATION

1.Check the bolt to fasten the blade and be sure the bolt has no fault, and no abrasion.

2.Be sure that the blade and the holder have been fastened according to instruction and the blade turns smoothly without abnormal noise. (OPT9)

WARNING

•The rotating parts fastened incorrectly may cause serious accident to the operator.

1. What causes blade thrust:

•Blade thrust can occur when the moving blade contacts an object that it cannot cut. This contact causes the blade to stop for an instant and then suddenly move or ”bounce” away from the object that was hit. The operator can lose control of the unit and the blade can cause serious personal injury to the operator or any person nearby if the blade contacts any part of the body.

2.How you can reduce the chance of blade thrust:

a.Recognize that blade thrust can happen. By understanding and knowing about bounce, you can help eliminate the element of surprise.

b.Cut fibrous weeds and grass only. Do not let the blade contact materials it cannot cut such as hard, woody vines and brush or rocks, fences, metal, etc

c.Be extra prepared for blade thrust if you must cut where you cannot see the blade making contact such as in

BCZ2450S/T

12. Optional blade usage (for BCZ2450S only)

areas of dense growth.

d.Keep the blade sharp. A dull blade increase the chance of blade thrust.

e.Avoid feeding the blade too rapidly. The blade can bounce away from material being cut if the blade is fed faster than its cutting capability.

f.Cut only from your right to your left.

g.Keep your path of advance clear of material that has been cut and other debris.

3.How you can maintain the best control:

a.Keep a good, firm grip on the unit with both hands. A firm grip can help neutralize bounce. Keep your right and left hands completely around the respective handles.

b.Keep both feet spread apart in a comfortable stance and yet braced for the possibility that the unit could bounce. Do not overreach. Keep firm footing and balance.
