Lesson

1

Maintain Electric and Hydraulic Tools

Maintenance is an action an item in or to restore it to its functional condition.

Regular maintenance and servicing of power tools and electric tools and electric tools

will help to ensure that they operate with optimum efficiency at all times.

The first thing to do in any preventive maintenance system is to use your eyes,

nose, ears, experience, and judgement. Follow your instinct or your keen observation

on an equipment when doing preventive maintenance.

PLANNED MAINTENANCE

1. Preventive maintenance is performed in order to ensure that the tools are

operating properly and efficiently.

2. Corrective maintenance is performed in order to correct a failure.

3. Emergency maintenance is necessary to put the item at hold immediately to

avoid serious consequences such as the loss of production, extensive damage

of assets, and for safety reasons.

4. LUBRICATION the following features contribute to safety and economic

lubricating machine tools:

1. Plates on machines clearly show the grades of lubricant, quantities and

intervals are required. The machine name, type, and model should be

visible.

2. Maintain the proper level of lubrication reservoirs.

3. Suitable method of lubrication should be followed to minimize or

prevent metal- to-metal contact at all times.

4. Sufficient lubricant capacity is needed to prevent overheating and

thermal distortion of machine tool structures.

5. Adequate sealing should be properly observed. Install provision for

removal of contaminant collected by the lubricant (e.g., filters)

Lesson Information 3.1

Learning Objectives: After Reading this module you must be able to explain how to handle safely

electrical power and hydraulic tools.

Safe Handling and Operating Principle of Power Tools Power tools must be fitted with guards and safety switches; they are extremely

hazardous when used improperly.

To prevent hazards associated with the use of power tools, workers should observe

the following general precautions:

1. Never carry a tool by the cord or hose.

2. Never yank the cord or the hose to disconnect it from the receptacle.

3. Keep cords and hoses away from heat, oil, and sharp edges.

4. Disconnect tools when not using them, before servicing and cleaning them,

and when changing accessories such as blades, bits, and cutters.

5. Keep all people not involved with the work at a safe distance from the work

area.

7. Secure work with clamps or a vise, freeing both and to operate the tool.

8. Avoid accidental starting.

9. Do not hold fingers on the switch button while carrying a plugged-in tool.

10. Maintain tools with care; keep them sharp and clean for best performance.

11. Follow instructions in the user’s manual for lubricating and changing

accessories.

12. Be sure to keep good footing and maintain good balance when operating

power tools.

13. Wear proper apparel for the task. Loose clothing, ties, or jewelry can

become caught in moving parts.

14. Remove all damaged portable electric tools from use and tag them:

“Do Not Use.”

Safe Handling and Operating Principle of Hydraulic Tools

15. Read and understand the entire owner's manual before attempting

assembly or operation.

16. Read and understand the warnings posted on the machine and in this

manual. Failure to all of these warnings may cause serious injury.

17. Replace the warning labels if they become obscured or removed.

What is It

10

18. Hydraulic Tools are designed and intended only if you are not familiar

with the proper and safe operation of a pipe bender, do not use until

proper training and knowledge have been obtained.

19. Before operating Hydraulic Tools (Pipe Bender), remove tie, rings, watches

and other jewelry, and roll sleeves up past the elbows. Remove all loose

clothing and confine long hair. Non-slip footwear or anti-skid floor strips

are recommended. Do not wear gloves.

20. Do not operate Hydraulic tools while tired or under the influence of drugs,

alcohol or any medication.

21. Check damaged parts. Before further use of the machine, a guard or ot

her part that is damaged should be carefully checked to determine that it

will operate properly and perform it is intended function. Check for

alignment of moving parts, binding of moving parts, breakage of parts,

mounting and any other conditions that may affect it is operation. A guard

or other part that is damaged should be properly repaired or replaced.

22. Provide for adequate space surrounding work area and non-glare,

overhead lighting.

23. Keep the floor around the machine clean and free of scrap material, oil

and grease.

24. Keep visitors a safe distance from the work area. Keep children away.

25. Give your work undivided attention. Looking around, carrying on a

conversation and “horse-play” are careless acts that can result in serious

injury.

26. Maintain a balanced stance and do not overreach or us excessive force to

perform any machine operation.

27. Use the right tool. Do not force a tool or attachment to do a job for which

it was not designed. The right tool will do the job better and safer.

28. Use recommended accessories; improper accessories maybe hazardous.

29. Maintain tools with care and clean for the best and safest performance.

Follow instructions for lubricating and changing accessories.

Note:

Familiarize yourself with the following safety notices found in manuals:

This means that if precautions are not heeded or observed, it may result in minor

injury and/or possible machine damage.
