Do not operate this machine unless you have

read and understand the instructions in the

OPERATOR’S MANUAL. Improper machine

operation is dangerous and could result in injury

or death.

Relieve all pressure in air, oil or water systems

before any lines, fittings or related items are

disconnected or removed. Always make sure

all raised components are blocked correctly

and be alert for possible pressure when

disconnecting any device from a system that

utilizes pressure.

Lower the bucket, blade or other attachments

to the ground before performing any work on

the machine. If this cannot be done, make sure

the bucket, blade or other attachment is

blocked correctly to prevent it from dropping

unexpectedly.

Use steps and grab handles when mounting or

dismounting a machine. Clean any mud,

grease, oil or debris from steps, walkways or

work platforms before using. Always face the

machine when using steps, ladders and

walkways. When it is not possible to use the

designed access system, provide ladders,

scaffolds, or work platforms to perform safe

repair operations.

To avoid back injury, use a hoist when lifting

components which weigh 23 kg (50 lbs) or

more. Make sure all chains, hooks, slings, etc.,

are in good condition and are the correct

capacity. Be sure hooks are positioned

correctly. Lifting eyes are not to be side loaded

during a lifting operation.

10. To avoid burns, be alert for hot parts on

machines which have just been stopped and

hot fluids in lines, tubes and components.

11. Be careful when removing cover plates.

Gradually back off the last two bolts or nuts

located at opposite ends of the cover or device

and carefully pry cover loose to relieve any

spring or other pressure, before removing the

last two bolts or nuts completely.

12. Be careful when removing filler caps,

breathers and plugs on the machine. Hold a

rag over the cap or plug to prevent being

sprayed or splashed by liquids under pressure.

The danger is even greater if the machine has

just been stopped because fluids can be hot.

13. Always use the proper tools that are in good

condition and that are suited for the job at

hand. Be sure you understand how to use

them before performing any service work.

14. Reinstall all fasteners with the same part

number. Do not use a lesser quality fastener if

replacements are necessary.

SAFETY PRECAUTIONS

1.2

SAFETY PRECAUTIONS

The serviceman or mechanic may be unfamiliar

with many of the systems on this machine. This

makes it important to use caution when

performing service work. A knowledge of the

system and or components is important before

the removal or disassembly of any component.

Because of the size of some of the machine

components, the serviceman or mechanic

should check the weights noted in this manual.

Use proper lifting procedures when removing

any components. Weight of components table

for SK40SR-2 / SK45SR-2 is shown in page

02-1-7, 8 of chapter SPECIFICATIONS in this

manual.

The following is a list of basic precautions that must

always be observed.
1.

Read and understand all warning plates and

decals on the machine before operating,

maintaining or repairing this machine.

Always wear protective glasses and protective

shoes when working around machines. In

particular, wear protective glasses when using

hammers, punches or drifts on any part of the

machine or attachments. Use welders gloves,

hood/goggles, apron and the protective

clothing appropriate to the welding job being

performed. Do not wear loose fitting or torn

clothing. Remove all rings from fingers, loose

jewelry, confine long hair and loose clothing

before working on this machinery.

Disconnect the battery and hang a “Do Not

Operate” tag in the operator’s compartment.

remove ignition keys.

If possible, make all repairs with the machine

parked on a level, hard surface. Block the

machine so it does not roll while working on or

under the machine. Hang a “Do Not Operate”

tag in the operator’s compartment.

Do not work on any machine that is supported

only by lift, jacks or a hoist. Always use blocks

or jack stands, capable of supporting the

machine, before performing any disassembly.
