Operator / Technical Manual

Struck Corp. - Cedarburg, WI 53012

Important Facts &

Tips for

Top Performance

The following are facts that will be expanded on

within this Manual. They are brought to you “first”

to impress upon you their primary importance in

preventing damage to your RT1150, understand-

ing how to operate the unit, and also to protect

your safety and prevent costly and unnecessary

maintenance expenses.

SAFE BLOCKING AREA

When “blocking” your Crawler off the ground for

service, be aware that you should only apply a

hydraulic jack, in the “Black Shaded” areas

marked below.

POWER VS. SPEED

The greatest amount of “Power” (drawbar

torque) your RT1150 can deliver is by pushing

the track drive handles: 1/4 of the way forward

and/or rearward. The greatest amount of

“Speed” your RT1150 can deliver is by pushing

the track drive handles: fully forward and/or

rearward.

Doing your tough/heavy work at approx. 1/2

thottle & slower travel speeds accomplishes a

few things:

1. It keeps the engine cooler.

2. It gives your RT1150 maximum draw

bar torque.

3. It provides time to make “attachment

adjustments” on the go!

You’re encouraged to completely read this Man-

ual to get a firm over-view of: how your RT1150

operates, significant safety points, and also main-

tenance tips on how to increase your MAGNA-

TRAC’S life.

PARKING BRAKE

NEVER FORGET to take off your Parking Brake...

BEFORE you drive away. If you fail to disengage

the Parking Brake, it can cause damage to the

hydro-static transaxles!

DRIVE BELT

It is strongly advised that you thoroughly read the

Drive Belt Removal & Installation chapter in the

Service Section of this Manual to give you an

over-view of the mechanics of your hydro-static

drive system.

In factory tests of different driving techniques, we

found that Drive Belt life will range from 100 to 400

hours. This testing proved that the operator is the

greatest variable in determining Belt life. From

these tests, the following driving rules have

evolved. If followed, they will give you the best

Belt life consistent with the severity of work you

are doing.

1. If your MAGNATRAC cannot push a particular

load you have two options:

A. Immediately reduce the load (raise the

Bucket or Blade) or...

B. Backup and take a new angle at the

load.

Never hold your track controls in a fixed posi-

tion (forward or rearward) against an immov-

able object for a long period of time, you will

unnecessarily wear the drive belt.

2. Your MAGNATRAC has outstanding pushing

ability, but it’s up to you, the operator, to use its

ability in the most efficient and economical man-

ner.

Support Areas

TRACTION & TRACKS

The track system of your MAGNATRAC is the re-

sult of over 60 years of experience.

A few helpful hints are listed below, that if followed,

will give you maximum track performance.

1. Avoid Overloading Your Track System. The

track system is designed to absorb a great deal of

material, but the less you force it to “digest”, the

greater the track’s stability and overall life.

When working the machine, clear a “driving path”

with the front attachment (Blade, Bucket, etc.) you

are using. Avoid climbing in loose material and

counter-rotating your tracks. This action will “cork-

screw” the Tracks into the pile and force unnec-

essarily large amounts of material into the Tracks.

2. Keeping Up with Track Tensioning. Properly

tensioning your tracks will allow the most reliable

and stable track system. Loose tracks, and/or front

idler mis-alingment is the main cause of track de-

railment. Please see proper tensioning in the

Service section of this manual.

3. Work Smartly when Excavating. The RT1150

can do alot of tough homeowner work. However,

when excavating an area, we advise to use the

backhoe to dig, or to use our Hydro Rear Hitch &

Three Shank Ripper to loosen the soil first. Then

come through the area with a front bucket or

blade, for moving the loosened material. This al-

lows you to use the power of the RT1150 smartly

& efficiently.

LUBRICATION

The consistent greasing of all moving joints, where

grease zerks are present, will greatly extend the

life of your equipment. However, the rear drive

chains should NOT be lubricated with grease.

We advise to spray on, non-detergent aersol

Chain & Wire Rope Lubricant, approx. every 50

hours. We use CRC®brand, Grainger®Item

#2F139.

ROLL-OVER STRUCTURE

AND INCLINES

The MAGNATRACS low center of gravity and

ground gripping traction, are no substitute for this

safety struture. A must if using the MAGNATRAC

in a business.

CAUTION: For safe operation on in-

clines, or when driving out of a ditch or

excavation area when a Backhoe is

mounted, we advise to drive in reverse

when going up slopes.

HYDROSTATIC TRANSAXLES

Other than recommended transaxle oil and filter

changes, the transaxle normally will not require

servicing during the life of the vehicle in which it is

installed. Should servicing be required, the exte-

rior of the transaxle will need to be thoroughly

cleaned. Do NOT use a pressure washer to

clean the unit. A Transaxle Service & Repair

Manual is included with this manual.

HOUR & TACH METER

The hour meter is based on actual engine run

hours. Alerts begin flashing a warning 4 hours be-

fore service is due, and will automatically reset 1

hour after the service interval. The meter displays

RPM while engine is running, and hours while en-

gine is off.

1. It will flash “LUBE” at 25 hour service inter-

vals. Please see the 25 hour service section of this

manual.

2. It will flash “CHG OIL” at 100 hour service in-

tervals. Please see the 100 hour service section of

this manual.

Tighten loose fittings. If hoses are kinked, install

new parts.

NOISE PROTECTION

Prolonged exposure to loud noise can cause im-

pairment or loss of hearing. Wear a suitable hear-

ing protective device such as earplugs to protect

against objectionable or uncomfortably loud noise.

START ENGINE ONLY FROM THE

OPERATOR’S SEAT!

Avoid possible injury or death from Crawler run-

away.

Do not start Engine by shorting across starter so-

lenoid terminals. Crawler may start and move if

normal circuitry is bypassed.

CAUTION: Never start Engine while

standing on ground. Start Engine only

from operator’s seat, with Brake en-

gaged.

Inspect your Crawler carefully each day before

you start it. See “Pre-Start Inspection”.

Clean your Crawler regularly.

INTRODUCTION: The turn

demonstrated (above) is the key to

your Crawler’s superior maneuver-

ability. It is accomplished with only

two controls, the A& B Left & Right

Track Controls. The illustrations

(below) show how to maneuver

your crawler in other turns.

MOVING FORWARD:

To move straight ahead, simulta-

neously push forward on both Left

and Right Track Controls.

MOVING REARWARD:

To move straight rearward, simultaneously pull

rearward on both Left and Right Track Controls.

TURNING RIGHT:

To turn sharply right, push forward on Left Track

Control while holding Right Track Control in neu-

tral.

TURNING LEFT:

To turn sharply left, push forward on Right Track

Control while holding Left Track Control in neutral.

COUNTER-ROTATING TRACKS

To counter-rotate Tracks (tightest turn possible),

push one Track Control forward while simultane-

ously pulling rearward on the other Track Control.

NOTE: When either Track Control is “slowly” re-

leased, it will automatically return to neutral.

NEVER allow Track Controls to “snap-back” to

neutral. See OPERATION section of this manual

for further instructions.

C - THROTTLE/CHOKE CONTROL (ITC)

The throttle and choke are combined into one

sturdy handle.

For COLD ENGINE STARTS, pull handle upward

to the “Choke” position, as far upward as pos-

sible. As soon as the engine starts, move handle

into the “Throttle” range.

For WARM ENGINE STARTS, (when you have

been using the unit and the engine is warm), move

the handle to the “High Throttle” position. As

soon as the engine starts, move handle into the

“Throttle” range.

Adjust handle as needed in the Throttle position

of choice. Fuel comsumption is better at lower

ranges. Adjusting your Power vs. Speed is

done mostly in the Left & Right Track Drive

Controls. Push the track drive controls “slightly”

forward or rearward to achieve “maximum

power”. Push the track drive controls “fully” for-

ward or rearward to achieve “maximum speed”.

Though all crawlers by their design are somewhat

“rough riding”, you can minimize the “roughness”

by traveling at the lowest speeds when going over

hard surfaces.

Before turning off tractor, move Throttle/Choke

Control handle to the ON SHUT- OFF position.

D - HEADLIGHT SWITCH (If equipped)

The Headlight Switch is a basic “Pull ON”, “Push

OFF” switch. Behind the dash, in the wiring har-

ness, is a replaceable Safety Fuse. When replac

ing, use a new fuse of the same amps as the one

being replaced.

E - KEY IGNITION SWITCH

Switch is activated by rotating key clockwise.

Turning it fully clockwise will engage engine starter

...release key and it will return automatically to the

RUN “ON” position. Turn fully counter-clockwise

to OFF position to stop engine. Remove key.

F - HOUR METER /TACH (If equipped)

The Hour Meter/Tach dis-

plays the hours run and the

RPM of the engine. Keeping

up with your maintenance of

your MAGNATRAC keeps it

running in top condition!

Flashes “CHG OIL” at 100 hour service intervals

and “LUBE” at 25 hour service intervals, the

service interval is based on actual run hours.

OPERATION & SERVICE RESET:

Alerts begin flashing a warning 4 hours before

service is due, and clear automatically 1 hour af-

terward. Meter displays RPM while engine is run-

ning, hours while engine is off. Service alarms will

automatically reset 1 hour after service interval.

G - FUEL VALVE LEVER

The Fuel Shut Off Valve Lever controls the fuel to

the carburetor. Turn it OFF for transport or when

cleaning carburetor. (Consult Engine Manual for

more information).

The fuel valve lever can be accessed by reaching

your arm under the grill. The decal shown below

will point to the area.

H - PARKING BRAKE

The Parking Brake acts both as a parking brake

and as an emergency brake.

To “engage” Parking Brake, pull Brake Handle up

firmly and loop it “up and over”the Carriage Bolt

provided...make sure handle edge is on top of Bolt

and behind “inside face” of Carriage Bolt.

To “disengage” Parking Brake, reverse the above

procedure and allow Brake Handle to rest down-

ward.

As the Parking Brake is also your emergency

brake, it’s extremely important to maintain its per-

formance with daily inspection. See Service sec-

tion of this manual for proper procedures.

EXTREMELY IMPORTANT:

As it’s mandatory to engage the Parking Brake be-

fore starting your crawler, always remember to

disengage it before driving away.

If you fail to disengage the Parking

Brake it can damage your transaxles

and be of no value in an emer-

gency!!!

each day, perform the following checks:

ENGINE & TRANSAXLE COMPARTMENT

Check engine oil level.

Check engine air intake system.

Remove trash and oil/dirt deposits.

Inspect drive belt & pulley conditions.

Inspect oil level of transaxles.

Inspect control linkage of transaxles.

Inspect bypass mechanism of transaxles.

TRACKS & ATTACHMENTS

Check for bent, broken, or missing parts.

Check Track Springs.

HARDWARE

Check for loose or missing parts.

ELECTRICAL SYSTEM

Check for worn or frayed wires or loose

connections.

LUBRICATION

Check lubrication points shown in Periodic

Service section of this Manual.

GUARDS AND SHIELDS

Check for tightness and condition.

BATTERY COMPARTMENT

Remove trash.

Check cables for tightness and corrosion.

FUEL TANK

Check fuel level.

OPERATOR’S STATION

Check control levers for free movement.

Clean fenders and instrument panel.

Adjust Seat location to fit operator.

CAUTION - Before you start the engine:

Clear the work area of people and obsta

cles.

Check the condition of the Crawler.

(Prestart inspection).

Be sure there is enough ventilation.

Be sure to know the correct starting and

stopping procedure.

Sit in the Operator’s Seat.

PREPARE FOR ENGINE STARTING

1. Allow Left (A) and Right (B) Track Controls to

assume their natural “spring-loaded” center neu-

tral positions.

2. Engage Parking Brake (H). (Make sure Brake

lever is pulled “up and over” round head of Car-

riage Bolt provided...make sure handle “edge” is

on top of this Bolt and behind its inside face).

3. Check that all Attachments are in the fully low-

ered position.

4. Make sure you are properly seated so Seat

Safety Switch will engage

STARTING THE ENGINE

The throttle and choke are combined into one

sturdy handle.

1a. For COLD ENGINE STARTS, pull handle up-

ward to the “Choke” position, as far upward as

possible. As soon as the engine starts, move

handle into the “Throttle” range.

NOTE: After starting a “cold” Engine, it may be

necessary to leave the handle in the “choke” po-

sition for a minute, before moving it to the “Throt-

tle” position.

1b. For WARM ENGINE STARTS, (when you

have been using the unit and the engine is warm),

move the handle to the “High Throttle” position.

As soon as the engine starts, move handle into

the “Throttle” range.

CAUTION: Do not crank the Engine

continuously for more than 10 seconds

at a time. If the Engine does not start,

allow a 60-second cool-down period be-

tween starting attempts. Failure to follow these

guidelines can burn out the starter motor.

CAUTION: If the Engine develops suffi-

cient speed to disengage the starter but

does not keep running (a “false start”),

the Engine rotation must be allowed to

come to a complete stop before attempting to

restart the Engine.

If the starter is engaged while the flywheel is ro-

tating, the starter pinion and flywheel ring gear

may clash, resulting in damage to the starter.

If the starter does not turn the Engine over, shut off

starter immediately. Do not make further attempts

to start the Engine until the condition is corrected.

If the battery charge is not sufficient to turn over

the Engine, recharge the battery.

CAUTION: Do not attempt to jump start

the Engine with another battery. Start-

ing with batteries larger than those rec-

ommended can burn out starter motor.

WARM-UP PERIOD

Run Engine at half throttle for 5 minutes.

Do not run Engine at fast, or slow idle.

Operate Crawler at less-than-normal loads and

speeds for the first 15 minutes.

WARNING: Lethal Exhaust Gases!

Engine exhaust gases contain poison-

ous carbon monoxide. Avoid inhaling

fumes, and never run the Engine in a

closed building or confined area.

NOTE: Assembled Crawlers are “run in”

under no load at the factory to properly

break-in their transaxles.

TRAVELING

Disengage Parking Brake (H); Fully raise all At-

tachments to recommended traveling heights.

To move straight ahead, simultaneously push

both Left Track Control (A) and Right Track Con-

trol (B) forward.

To move straight to the rear, simultaneously pull

both Right and Left Track Controls rearward.

To turn sharply to the right, push Left Track

Control fully forward...leave Right Track Control in

neutral.

To turn slowly to the right, push Left Track Con-

trol fully forward while simultaneously pushing

“partially” forward on Right Track Control...the far-

ther you push the Right Track Control forward, the

slower you will turn right.

To turn sharply to the left, push Right Track

Control fully forward...leave Left Track Control in

neutral.

To turn slowly to the left, push Right Track Con-

trol fully forward while simultaneously pushing

“partially” forward on the Left Track Control...the

farther you push the Left Track Control forward,

the slower you will turn to the left.

To counter-rotate Tracks, (shortest turn possi-

ble), push one Track Control forward while simul-

taneously pulling rearward on the other Track

Control. You may counter-rotate “clockwise” or

“counter-clockwise”; move in which ever direction

satisfies the job at hand.

Stopping the Crawler: The Right and Left Track

Controls are of the self-centering (neutral) type.

This allows you to simply release pressure on both

Track Controls to disconnect active power to the

Tracks and come to a complete stop. Never

“snap” Track Controls back into neutral! Dam-

age to the hydrostatic transaxles may occur.

PARKING THE CRAWLER

1. Lower all Attachments to the ground.

2. Allow Right and Left Track Controls

to go “slowly” to neutral.

3. Engage Parking Brake.

4. Run Engine at half speed 2 minutes

without load.

5. Move Throttle/Choke Control to low,

“ON SHUT-OFF”.

6. Turn Ignition Switch to Off.

IMPORTANT: If Engine stops under load, remove

load. Start Engine immediately. Run 30 seconds

at half speed before adding load.

CAUTION: When you park your

Crawler on a slope, put blocks against

tracks. Do not park Crawler with tracks

pointed downhill, always park “cross-

ways” to the hill!

STORAGE

Always store your MAGNATRAC in a garage,

shed or barn. If the only option is to park outside,

make sure to securely tarp the unit and park on a

flat surface with the parking brake engaged.

If Tracks are frozen to the ground, be careful to

avoid damage to the Tracks and transaxles when

you try to move the Crawler.

We advise to turn off the fuel shut off valve and

run until the unit stops if going to store for a long

period of time. This is to ensure easy starting dur-

ing the next season. Remember to turn ON the

fuel when ready for work the next time!

5- DRIVE BELT, FUELS

& LUBRICANTS

BELT

DRIVE BELT

Your RT1150 is equipped with a #004520 Oil &

Heat Resistant, Hi-Power II Double V Drive

Belt. This drive belt powers your left & right hy-

drostatic transaxles, as well as your hydraulic at-

tachment pump.

FUELS

FUEL SPECIFICATIONS

Add fuel to fuel tank per engine manual specs.

Unleaded 86 octane or higher is recc-

ommended per HONDA. Verify fuel shut-

off valve is in the open position.

FILLING FUEL TANK

The Fuel Tank is located underneath the hood, on

the engine.

Fuel Tank capacity is 0.61 US gallons.

Use unleaded gasoline per Engine Owner’s Man-

ual.

CAUTION: Handle fuel carefully. Do

not fill fuel tank when the Engine is run-

ning. Do not smoke while you fill fuel

tank or work on fuel system.

STORING FUELS

Keep fuel in a container in a protected area.

Water and sediment must be removed before fuel

gets to the Engine. Do not depend on fuel filters

to remove water.

IMPORTANT: Keep all dirt, scale, water, or other

foreign matter out of fuel.

LUBRICANTS

ENGINE OIL

Check enclosed Engine Owner’s Manual and

closely follow their recommendations. 10W30 is

recommended for general use.

TRANSAXLE OIL

Check enclosed Transaxle Manual and closely fol-

low their recommendations. Typically, an engine

oil with a minimum rating of 9.0cSt (55 SUS) at

230º F (110º C) and an API classification of SL is

recomended. A 20W50 engine oil has been se-

lected for use by the transaxle factory and is

recomended for normal operating conditions.

HYDRAULIC ATTACHMENT OIL

Use a premium quality hydraulic oil with maximum

anti-wear properties, rust and oxidation treatment.

We use an AW46 Hydraulic Oil. (ISO 46). If op-

erated at exteme hot or cold temperatures, please

consult a local oil shop for an oil viscosity best

suited for your conditions.

GREASE

Use premium quality SAE Multi-Purpose Grease

in a grease gun, with a flexible “nose” to lubricate

grease zerks throughout the MAGNATRACS pivot

points. Recommended grease: Multipurpose

NLGI 2 Grade Lithium Complex, ISO VG 220.

REAR DRIVE CHAIN LUBRICATION

At a minimum...brush on SAE 30 weight oil (non-

detergent) on rear drive chains. A more expen-

sive, but cleaner option is to use a spray lubricant,

such as: non detergent aerosol Chain & Wire

Rope Lubricant. We use CRC® brand,

Grainger® Item #2F139. Both of these methods

are acceptable lubrication options.

STORING LUBRICANTS

Store lubricants in clean containers in an area pro-

tected from dust, moisture, etc.
