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!
