C. F. STRUCK CORPORATION

Cedarburg, Wisconsin 53012

Dear Magnatrac Owner:

Working with thousands of customers over the last 38 years, I’ve gained some tips that I would

like to share with you to make your Magnatrac experience as safe and rewarding as possible.

When a customer first receives his new Magnatrac he grabs the keys, fires-up the engine

and dives into his first big job. This is human nature and quite understandable, but experi-

ence has shown that such action is DANGEROUS to the operator and can lead to unnecessary

and costly damage to the Magnatrac.

As a Magnatrac Operator/Mechanic, you are expected to understand your crawler’s opera-

tion & safety, basic mechanical construction, and proper maintenance. All the information you

need is in the following Operator Manual! Take time NOW, beforeyou start to operate your

Magnatrac, to go over the complete Manual. Read in detail the operating, and safety instruc-

tions. Read for “background” other sections such as lubrication, service, etc...you can go back

later for more detailed reading when you actually have to perform those operations.

In conclusion, I want to bring two critical topics to your attention: Periodic Maintenance &

Tractor Operation. Experience shows that many operators let these areas go, creating either

dangerous situations for themselves or needless damage and subsequently expensive repairs.

By taking the following three points seriously, you can make your Magnatrac experience

satisfying, profitable, but above all...SAFE!

Sincerely yours,

#1 - PERIODIC MAINTENANCE:

Though periodic maintenance is well covered in the Operator’s Manual, it seems that some opera-

tors have let some points “slide” and have suffered expensive repairs. In the hopes of saving you

from premature failure in the future, due to forgotten maintenance, the following points are brought

to your attention!

1) The #526 Bushings (steel) which restrains the #525 Torque Arms mounted to the #524 Track Drive

Motors must be replaced before they wear through and damage their mating #202C Pin. [Check

Drawings MH-2 & MH-3].

2) The #536 & 1090 Chains should be checked for proper tensioning. See “DRIVE CHAIN TEN-

SIONING” in Service section of your Operator Manual for complete instructions.

Failure to inspect and properly tension the chains can result in stripped sprocket teeth and exten-

sive repair work.

3) #1210R & #1210L Right & Left Guards, must be periodically removed and cleaned. Located under

the crawler, these guards protect the#1090 Chain from being damaged (see Photo MH-29).

Due to the varied materials your tractor operates in, there is no specific maintenance schedule for

these #1210 Guards. Rather it is up to the operator to gain experience with the use of the Guards

and create his own maintenance schedule...the Guards may require daily removal and cleaning if

the tracks are run all day submerged in mud, or it may be monthly or quarterly maintenance

because your tractor is working in a relatively clean environment like grass.

4) Grease is good. Consistent lubrication of all moving joints will greatly extend the life of your

equipment, with one exception. The #536 & #1090 Drive Chains should not be lubricated with a

thick or sticky lubricant as this will promote the adhesion of abrasive material.

#2 - CRAWLER OPERATION...Uphill and Downhill:

It can not be repeated too often that you must operate your Track Control handles slowly and

smoothly...they control a hydraulic drive system that can produce literally “tons of physical force”.

But in addition, the Track Controls can also produce an opposite force or “resistance to move-

ment” when going up and down hills with heavy loads...in other words, they can provide a dynamic

braking action!

EXAMPLE

Potentially, if you are going downhill with a load that exceeds factory recommendations, you may

find that your “overload” is actually pushing you downhill faster than the crawler’s drive system is

propelling you down the hill. Under these circumstances you have basically two steps for safe control

of your crawler:

First, slowly release the Track Controls so that they may go to neutral and provide a dynamic

braking action. Again, it must be emphasized that you must operate your Track Controls

slowly. Remember, you are controlling tons of force, and though significant overload strength

has been built into the Controls, you still can do serious damage to your tractor’s hydraulic

drive by “snapping” the Controls into the neutral position. The act of snapping the Controls to

neutral is equivalent to driving your car down the highway at 65 miles per hour and then

instantly shifting into reverse!

The second step in controlling your crawler is to apply your Parking/Emergency Brake. This is an

over-ride braking action used to augment the hydraulic system’s dynamic braking effect. Again, to

protect your drive system from harmful shock loads, the brakes, like the Track Controls, must be

applied with controlled force...never in a snapping action.

SUMMARY

Your crawler should always be operated with forethought, rather than in a series of sudden, and

potentially damaging, starts and stops. Always plan your crawler movements so as to eliminate the

need for any potentially damaging sudden Track Control or Brake operation. * NEVER carry or move

loads in excess of factory recommendations! *

******* As always, you are encouraged to contact the factory if you have any questions regarding the

above instructions, or for more information regarding other maintenance and operational procedures!

2- SAFETY RULES

Reports on accidents show that careless use of

machinery causes a high percentage of accidents.

You can avoid many accidents by following the

safety rules on these pages. Study these rules

carefully and enforce them on the job.

SAFETY BEFORE STARTING OR

OPERATING

•The Crawler should be operated only by

persons approved to do so.

•Clothing worn by the operator should be fairly

tight and belted.

•Fasten a first aid kit to the Crawler.

•Fasten a fire extinguisher to the Crawler.

Keep the extinguisher fully charged. Learn to

use it correctly.

•If the Crawler has an unsafe condition, do not

operate. Put a tag on the Track Drive

Controls.

•Do not start or operate the Crawler unless you

are in the operator’s seat.

•Before you start the Engine, be sure there is

plenty of ventilation.

•Keep hands, feet, and clothing away from

power-driven parts.

•Fasten a slow-moving vehicle sign to the rear

of the Crawler.

•Do not change Backhoe or Loader relief valve

setting without consulting factory.

•Before you operate Backhoe, be sure

stabilizers are in correct position.

•Before you start or operate the Crawler, clear

the area of all persons and obstacles.

•Guards, shields, and other protective devices

must be in place and in good condition.

OPERATION SAFETY

•When you operate the Crawler, do not allow

anyone to ride on the Crawler or its

equipment.

•Drive at safe speeds at all times, especially on

rough ground and hillsides.

•Carry the Bucket or Blade as low as possible

at all times, especially when you work on a

hillside or back up a steep hill.

•Do not lower a loaded Bucket or Fork with the

control lever in float position.

•Do not drive too close to the edge of a ditch or

excavation.

•Watch for overhead wires. Do not touch wires

with any part of the Crawler or its Attachments.

•Do not leave your Crawler unattended with the

Engine running.

•Keep work areas as level as possible.

•Do not operate the Crawler Loader without the

minimum recommended counterweights.

•Do not dig under stabilizers of Crawler with the

Backhoe.

•When loading logs with the Log Forks, make

sure the logs are balanced.

•Before you transport the Backhoe, attach the

safety chains provided.

•When you drive out of a ditch or excavation, or

up a steep hillside, or when Crawler is hitched

to a heavy load, engage Track Drive Controls

slowly. If the front of the Crawler comes off the

ground, release Track Controls immediately.

•When you operate the Backhoe on a hillside,

avoid swinging Bucket downhill. If possible,

dump Bucket on the uphill side.

•Before you lower any hydraulic equipment, be

sure all persons are away from the Crawler.

•Do not use the Crawler as a battering ram.

•Do not guide cable onto Winch Drum with your

hands.

•When you drive the Crawler on a road, use the

correct lights to warn operators of other

vehicles.

•Before you move any equipment, be sure all

persons are away from the Crawler.

•When the Crawler is operating, only the

operator should be on it.

•If it is necessary to make checks with the

Engine running, always use two people...the

operator at the controls, should be able to see

the person doing the checking.

KEEP HANDS AWAY FROM MOVING PARTS.

DANGER: Never use “quick-disconnect”

type couplings on this Crawler or any of its

mating Attachments unless specified; to do so

results in the potential of rupturing hydraulic

fittings or even “blowing-up” your hydraulic

pumps!

BEFORE YOU DISMOUNT:

1) Move Track Drive Controls to neutral.

2) Push down Parking Brake and Lock.

3) Lower all equipment to the ground.

4) Stop Engine and remove the key.

SERVICE SAFETY

•Be sure you understand a service procedure

before you work on the Crawler.

•Unauthorized modifications to the Crawler

may impair the function and/or safety and

affect Crawler

life.

•Do not work

under raised

e q u i p m e n t

unless it is

c o r r e c t l y

supported.

•Before you

work on the

Engine or

e l e c t r i c a l

s y s t e m ,

d i s c o n n e c t

the battery’s

“ground” ( - )

terminal first!

When work is

finished, connect battery’s “ground” terminal (

- ) last.

•When driving connecting pins, wear goggles

or safety glasses.

•Do not run Engine while working on the

Crawler.

•Be careful when handling any type of fuel. Do

not smoke while filling the fuel tank or working

on the fuel system.

•Check for faulty wiring or loose connections.

•Do not lubricate or work on the Crawler while

it is moving.

•Release hydraulic pressure before working on

hydraulic system. Move every hydraulic

control lever back & forth until equipment does

not move.

•Before using the hydraulic system, be sure

that all connections are tight and that lines are

in good condition.

•When you work near the Track Springs, use

extreme care. Do not disassemble parts

unless you know the correct procedure and

have correct tools.

FIRE PREVENTION MAINTENANCE

•Be prepared if an accident or fire should occur.

Know where the first aid kit and the fire

extinguishers are located—know how to use

them. Check fire extinguisher for correct

charge.

•Do not smoke while refueling or handling

highly flammable material.

•Shut off the Engine when refueling.

•Use care in refueling if the Engine is hot.

•Do not use open pans of gasoline or diesel

fuel for cleaning parts. Use good commercial,

nonflammable solvents.

•Provide adequate ventilation when charging

battery.

•Do not check battery charge by placing metal

objects across the posts.

•Do not allow sparks or an open flame near

battery. Do not smoke near battery.

•Never check fuel, battery electrolyte, or

coolant levels with an open flame.

•Never use an open flame to look for leaks

anywhere on the equipment.

•Never use an open flame as light anywhere on

or around the equipment.

•When preparing Engine for storage,

remember that inhibitor is volatile and

therefore dangerous. Seal and tape openings

after adding the inhibitor. Keep container

tightly closed when not in use.

•Inspect electrical wiring for worn or frayed

insulation. Install new wiring if wires are

damaged.

•Temperature in Engine and cooling

compartments may go up immediately after

you stop the Engine. Be on guard for fires.

•Before you clean trash from the Engine

compartment, wait until the Engine has

cooled. Open Side Panels to cool the Engine

faster. While the Engine cools, clean trash

from other areas.

•Check for leaking fuel lines, hydraulic lines,

hoses, or fittings with a piece of cardboard or

wood. Do not use your hands. Tighten loose

fittings. If lines are bent or hoses kinked,

install new parts.

PROTECT AGAINST NOISE

Prolonged exposure to loud noise can cause

impairment or loss of hearing. Wear a suitable

hearing protective device such as earmuffs or

earplugs to protect against objectionable or

uncomfortable loud noise.

AVOID HIGH-PRESSURE FLUIDS

Escaping fluid under pressure can penetrate

the skin causing serious injury. Relieve pressure

before disconnecting hydraulic or other lines.

Tighten all connections before applying pressure.

Keep hands and body away from pinholes and

nozzles which eject fluids under high pressure.

Use a piece of cardboard or paper to search for

leaks. Do not use your hand.

If ANY fluid is injected into the skin, it must be

surgically removed within a few hours by a doctor

familiar with this type of injury or gangrene may

result.

INSTALL AND MAINTAIN ROPS

PROPERLY

If Roll-Over

P r o t e c t i v e

Equipment is

loosened or

removed for any

reason, make

certain all parts

are reinstalled

correctly. Tighten

mounting bolts to

proper torque.

The protection

offered by ROPS

will be impaired if

the ROPS is

subject to

s t r u c t u r a l

damage, has been involved in an overturn

incident or is in anyway altered. Damaged ROPS

should be replaced, not reused.

•DO use your Seat Belt if your Crawler has a

Roll-Over Protective Structure (ROPS).

•DO NOT use a Seat Belt if your Crawler does

not have a ROPS.

START ENGINE ONLY FROM THE

OPERATOR’S SEAT!

•Avoid possible injury or death from Crawler

runaway.

•Do not start Engine by shorting across starter

solenoid terminals. Crawler may start and

move if normal circuitry is bypassed.

•Never start Engine while standing on ground.

Start Engine only from operator’s seat, with

Parking Brake engaged.

•Inspect your Crawler carefully each day

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

•Clean your Crawler regularly.

WARNING: The Seat Assembly is

equipped with an electrical safety switch to

prevent starting and operating the crawler while

not occupying the seat. Disabling this feature

creates the potential for severe injury or death.

Engine speed...turn handle 1/4 turn clockwise to

lock throttle setting (Do not over-tighten!)

(G) FOOT THROTTLE CONTROL (MH7000 only)

The MH7000 is also equipped with a foot throttle

control to facilitate changes in engine speed

during operation. Locking the hand throttle at a

desired engine RPM will set determine the lowest

operating RPM when foot pedal is released.

(H) LIGHT SWITCH

Pull control handle toward

operator to turn lights on. Push

fully back to turn lights off.

(I) SEAT SAFETY SWITCH

The seat safety switch prevents operation of the

crawler when the operator is not positioned in the

seat. The safety switch may need to be adjusted

to the operator’s weight in order to operate

correctly. See the Service section of this manual

for adjustment procedures.

(J) IGNITION SWITCH

Switch is activated by rotating key

clockwise. Turning it fully clockwise

will engage Engine starter ...

release key and it will return to the

Run position. Turn fully counter-

clockwise to Off position to stop

Engine. Remove key.

AUXILIARY HYDRAULIC CONTROLS

An auxiliary bank of Control Valves is located

to the operator’s right. These valves are used to

control all attachments on your tractor. Your

particular tractor will contain from one to five of

these valves based on the attachments you have.

(K) OVERDRIVE/ACCESSORY CONTROL

This Overdrive/Accessory Control Valve has two

functions.

1) When pushed fully forward and “locked” into

the Overdrive position, this valve directs the oil

flow of the attachment pump into the track drive

system. When Track Drive Controls are activated,

this feature allows your tractor to gain extra speed

to get out of excavations or move quickly to dump

locations.

In addition, you can travel in “overdrive” for

lighter, higher speed operations. Your tractor will

automatically shift down to regular drive speed

whenever you change an attachment setting

(raise loader, tilt bucket, etc.) then shift back to

overdrive when you are through.

NOTE:The overdrive feature is not available on

the MH4800.

2) When pulled fully rearward and “locked” into

the Accessory position, it directs the oil flow to

optional attachments like our Backhoe, log splitter,

etc. Contact our Service Dept. for more

information on specific hydraulic flow rates,

pressures and various uses for this Accessory

setting.

CAUTION: With Control in “accessory

position” (and its mating Valve Port

plugged), all power to the tracks is lost! Do

not leave control in this position for any

period of time!

(L) FAN SWITCH

Your Magnatrac Hydro 7000

comes equipped with an

automotive type fan attached to its

external radiator. Turn fan on by

pulling switch to help reduce

hydraulic oil temperature in hot

conditions. Turn off fan during extensive use of

headlights to prevent excessive battery drain.

Abooster fan option is available for the

internal radiator of the MH4800, in which case

operation is as described above.

(M) HOUR METER (MH4800 option)

Meter will begin recording time

the moment the Ignition Switch

(O) is switched to Run.

NOTE: The Engine does not

have to be running for the Meter

to record time...the Ignition Switch

just has to be in the Run position. Always turn

Ignition Switch Off and remove key when leaving

Crawler. This will assure you that your Meter is

recording only actual running hours!

(N) TEMPERATURE GAUGE

This gauge records

the hydraulic oil

temperature just as it

enters the Traction Drive

Pump. Monitor this

temperature so that it

does not exceed 180

degrees Fahrenheit.

If the oil temperature exceeds 180 degrees,

stop operating the Crawler, but allow the Engine

to operate at medium speed to circulate the oil

through the radiator and lower its temperature.

(O) AMMETER (MH4800 option)

Measures electrical charge or

discharge to battery. If Ammeter

shows a discharge, shut down

electrical system by turning

Ignition Switch to Off and

determine the problem.

(P) HYDRAULIC CIRCUIT CONTROL (optional)

The Hydraulic Circuit Control distributes flow

to the optional HC74 Hydraulic Circuit kit. This

flow is utilized for the PTO70 Power Takeoff option

as well as for other full flow and high pressure

accessories (snow blower, auger, stump grinder,

etc...).

PRE-STARTING INSPECTION

Before you start your Crawler for the first

time each day, perform the following checks:

ENGINE COMPARTMENT

Check oil level.

Check air intake system.

Check fuel filter.

Remove trash and oil-dirt deposits.

GRILL AND SIDE PANELS

Remove trash.

Clean radiator.

TRACKS, ATTACHMENTS, SHEET METAL

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.

HYDRAULIC SYSTEM

Check for leaking lines and connections.

Check for bent or kinked lines.

Check for lines rubbing against each

other or against other parts.

Check oil level.

OPERATOR’S STATION

Check levers for free movement.

Check ROPS and Seat Belt.

Clean floor and instrument panel.

Adjust Seat to comfortable height for

operator.

CAUTION - Before you start the engine:

1) Check the condition of the Crawler. (Pre-start

inspection).

2) Be sure there is enough ventilation.

3) Be sure to know the correct starting and

stopping procedure.

4) Sit in the operator’s seat.

5) Clear the work area of people and obstacles.

IMPORTANT: Do not tow or push your

Crawler to start it. You may damage the

hydraulic drive system.

PREPARE FOR ENGINE STARTING

1) Fasten Seat Belt (only if you have ROPS

installed).

2) Allow Left (B) and Right (C) Track Controls to

assume their natural spring loaded center

neutral positions.

3) Push forward on Parking/Emergency Brake

(A) and lift up Lock/Release Handle (D) until

brake locks into position.

4) Check that Loader or front-mounted Bulldozer

Blade is in the fully lowered position, and that

the Backhoe is either in the chained safe

traveling position, or resting on the ground.

5) Check that all other hydraulic controls are in

their centered neutral position.

NOTE: The hydraulic Accessory Control

(T) does not have a spring loaded neutral

centering device; therefore, you must

move it back and forth to determine its

center-neutral position.

6) Make sure you are properly seated so Seat

Safety Switch will engage.

STARTING THE ENGINE

1) Place the Throttle Control (F) midway between

the Slow and Fast positions.

2) Activate the Ignition Switch (J) by rotating it

clockwise until starter engages. Release the

switch as soon as the Engine starts...Switch

will return to the Run position.

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 between

starting attempts. Failure to follow these

guidelines can burn out the starter motor.

CAUTION: If the Engine develops sufficient

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

rotating, 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. Starting with

batteries larger than those recommended

can burn out the starter motor.

WARM-UP PERIOD

1. Run Engine at half speed for 5 minutes.

2. Do not run Engine at fast, or slow idle.

3. Operate Crawler at less-than-normal loads

and speeds for the first 15 minutes.

WARNING: Lethal Exhaust Gases

Engine exhaust gases contain poisonous

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 for 20 - 30 minutes to

properly break-in their drive train and track drive

motors, and to test hydraulic systems.

USE SEAT BELT

CAUTION: Use a Seat Belt when you

operate with a Roll-Over Protective

Structure (ROPS) to minimize chance of

injury from an accident such as an overturn.

Do not use a Seat Belt if operating without a

ROPS.

TRAVELING

Push forward on Parking Brake (A) and lower

Brake Lock (D); slowly release pressure on

Parking Brake and allow it to come back to its

natural “rearward” position...remove foot from

Brake!

Raise all attachments to their recommended

traveling heights.

A) To move straight ahead, simultaneously

push Right Track Control (C) and Left

Track Control (B) forward.

B) To move straight to the rear, simultaneously

pull both Right and Left Track Controls

rearward.

C) To turn to the right, push Left Track Control

forward.

D) To turn to the left, push Right Track Control

forward.

E) To counter-rotate Tracks, (shortest turn

possible), push one Track Control forward

while simultaneously pulling rearward on

the other Track Control.

NOTE:The Right and Left Track Controls are

of the self-centering (neutral) “deadman” type.

This allows you to simply let go of both Track

Controls to disconnect active power to the Tracks.

F) Parking/Emergency Brake (A) will stop or

hold Crawler in the neutral drive position.

PARKING THE CRAWLER

1) Lower all equipment to the ground.

2) Allow Right and Left Track Controls to go to

neutral.

3) Push forward on Brake and lift lock handle to

engage parking brake.

4) Run Engine at half speed 2 minutes without

load.

5) Move Throttle Control to slow idle.

6) Turn Ignition Switch to Off.

7) Release hydraulic pressure by “rocking” all

hydraulic controls back and forth.

IMPORTANT: If Engine stops under load,

remove load. Start Engine immediately. Run 30

seconds at half speed before adding load.

NOTE: If engine stops, you must turn key Off

before you can start the engine.

IMPORTANT: In freezing weather, park on a

hard surface to avoid freezing the Tracks to the

ground. If Tracks are frozen to the ground, be

careful to avoid damage to the Tracks and drive

train when you try to move the Crawler.

CAUTION: When you park your Crawler

on a slope, put blocks against tracks. Do

not park Crawler with tracks pointed

downhill.

5- FUELS and LUBRICANTS

FUELS

FUEL SPECIFICATIONS

Check enclosed Engine Owner ’s Manual and
