O.S. GENUINE PARTS &ACCESSORIES

Remember that your engine is not a "toy", but a highly efficient internal-

combustion machine whose power is capable of harming you, or others, if it is

misused.

As owner, you, alone, are responsible for the safe operation of your engine, so act

with discretion and care at all times.

If at some future date, your O.S. engine is acquired by another person, we would

respectfully request that these instructions are also passed on to its new owner.

SAFETY INSTRUCTIONS AND WARNINGS ABOUT YOUR O.S. ENGINE

The advice which follows is grouped under two headings according to the

degree of damage or danger which might arise through misuse or neglect.

WARNINGS NOTES

These cover events which

might involve serious (in

extreme circumstances, even

fatal) injury.

These cover the many other

possibilities, generally less obvious

sources of danger, but which, under

certain circumstances, may also

cause damage or injury.

WARNINGS

••

•

Never touch, or allow any

object to come into contact

with, the rotating parts.

Model engine fuel is poison-

ous. Do not allow it to come

into contact with the eyes or

mouth. Always store it in a

clearly marked container and

out of the reach of children.

Model engine fuel is also

highly flammable. Keep it

away from open flame,

excessive heat, sources of

sparks,oranythingelsewhich

might ignite it. Do not smoke

orallowanyoneelsetosmoke,

near to it.

Model engines generate

considerable heat. Do not

touch any part of your

engine until it has cooled.

Contact with the muffler

(silencer), cylinder head or

exhaust header pipe, in

particular, may result in a

serious burn.

Never operate your engine in an en-

closed space. Model engines, like auto-

mobile engines, exhaust deadly carbon-

monoxide. Run your engine only in an

open area.

NOTES

•

These engine were designed for model

helicopters. Do not attempt to use it for any

other purpose.

Mount the engine in your model securely, fol-

lowing the manufacturers' recommendations,

using appropriate screws and locknuts.

Install an effective silencer (muffler). Frequent

close exposure to a noisy exhaust (especially

in the case of the more powerful high-speed

engines) may eventually impair your hearing

and such noise is also likely to cause

annoyance to others over a wide area.

Check the linkage to the throttle arm before

each flight.

Avoid sudden high r.p.m. immediately after the

engine is started, as the clutch will engage and

you may be struck by the rotor.

•

After starting the engine, carry out any needle-

valve readjustments after stopping the rotor by

closing the throttle to the lowest r.p.m..

Stop the engine before attempting to make

other adjustments to the carburetor.

Use an electric starter. The wearing of safety

glasses is also strongly recommended.

Press the rotor head down securely.

Take care that the glow plug clip or battery

leads do not come into contact with rotating

parts.

Adjust the throttle linkage so that the engine

stops when the throttle stick and trim lever on

the transmitter are fully retarded. Alternatively,

the engine may be stopped by cutting off the

fuel supply. Never try to stop the engine

physically.

•

NOTES

•

Take care that loose clothing (ties, shirt sleeves,

scarves etc.) do not come into contact with the

rotor. Do not carry loose objects (such as pen-

cils, screwdrivers, etc.) in a shirt pocket from

where they could fall through the rotor disc.

For their safety, keep all onlookers (especially

small children) well back (at least 20 feet or 6

metres) when preparing your model for flight. If

you have to carry the model to the take-off point

with the engine running, be especially cautious.

Hold the rotor securely and keep well clear of

spectators.

Warning! lmmediately after a glowplug-ignition

engine has been run and is still warm,

conditions sometimes exist whereby it is just

possible for the engine to restart when turned

over WITHOUT the glowplug battery being

reconnected. Remember this if you wish to

avoid the risk of accidents.

Because of initial tightness, a

standard electric starter may have

difficulty in rotating the engine when

cold, before it has been adequately

run-in. In this case, use a high-torque

type starter.

DO NOT, however, confuse tightness

with the symptoms of hydraulic lock

caused by an excess of fuel within the

cylinder - often the result of over-

priming.

Attempting to force the engine to turn

over in this condition may cause

internal damage. Instead, remove the

glowplug, invert the engine and eject

surplus fuel from the combustion-

chamber.

Note:

The MAX-61SX-H RING "WC" is an up-rated

version of the MAX-61SX-H RING helicopter

engine. It is aimed at FAI World

Championship(hence the suffix 'WC') Class

F3C competition. Performance has been

increased and the Type 60B carburetor has

been modified for easier adjustment. High

quality and high performance have been

confirmed in exhaustive flight testing and

in F3C contest results. The 61SX-H has a

traditional sideexhaust layout, whereas the

61RX-H features a rear exhaust for users

who prefer such a configuration. In all other

respects, the two models are of identical

design.

INSTALLING THE GLOWPLUG

Install the washer on the

glowplug and screw

carefully into cylinder-

head, making sure that it

is not cross-threaded

before tightening firmly. Glow plug

Washer

Cover Plate As delivered, the engine has its carburetor lightly

fitted into its intake boss. Secure it as follows.

INSTALLATION OF THE CARBURETOR

Retainer

Carburetor Rubber

Gasket

0.2mm gap

Loosen the retainer screw, rotate the carburetor to

its correct position and press it well down into the

intake boss, compressing the rubber gasket as

shown in the sketch, before re-tightening screw.

Rotate the retainer screw gently until it stops, then

tighten a further 120-180 degrees. Do not over-

tighten the screw as this will damage the thermo-

insulator.

Engine does not rest firmly.

Make sure that only the under-surfaces

of the engine’s mounting lugs are in

contact with the engine mount.

If the crankcase body touches the

mount, chamfer the edges of the mount.

INSTALLATION OF THE ENGINE

The under-surfaces of all O.S. engine beam

mounting lugs are precision machined flat and

exactyly parallel to the engine's horizontal axis. It is

essential that the engine mounts in the model are

also accurately made and aligned. If they are not,

they will cause stress and distortion within the engine

itself, probably resulting in loss of performance and

internal damage.

The recommended screws for securing the engine to

the engine mounts in the model are 4mm or 6-32 NC

steel Allen type. It is also advisable to use lock

washers or LOCTITE to prevent nuts from loosening.

3 Glowplug battery

The power source for heating the glowplug may be

either a large heavy-duty 1.5volt dry cell, or preferably,

a 2-volt rechargeable lead-acid cell .

1.5 volt heavy-duty

dry battery or 2 volt rechargeable

lead-acid cell (at least 5Ah)

If a 2-volt cell is employed,

use a resistance wire, as

shown, to reduce applied

voltage, otherwise element

will overheat and burn out.

Resistance coil

(nichrome wire)

Adjust applied voltage by changing the position of clip on

resistance coil until glowplug element is glowing bright red.

Battery leads

Raise

voltage to

increase

brightness.

Lower voltage to

reduce brightness.

Warning (Very hot)

Never touch the

nichrome wire

while the battery

is connected.

4 Plug wrench

Used for tightening glowplug. The

O.S. long plug wrench is available

as an optional accessory.

5 Battery leads

These are used to conduct current

from the battery to the glowplug.

Basically, two leads, with clips, are

required, but, for greater conve-

nience, twin leads with special

glowplug connectors, as shown on

the right, are commercially available.
