This is a detailed, practical, and professional documentMaintenance Guide for Leverage GaugeA lever gauge is a precision measuring instrument, with an extremely delicate and fragile internal mechanism (lever, gear, balance spring),Proper maintenance is the way to ensure its accuracy and lifespan.

Core Principles of Maintenance

Light, clean, cautious, and constant

• lightLight operation and storage.

• netKeep clean and free from dust and dirt.

• prudentUse with caution to avoid overloading.

• constantRegular check ups and habit formation.

Daily/After Use Maintenance

This is the most important preventive maintenance and should be carried out immediately after each use.

1. clean

• Gently wipe the lever gauge with a clothThe entire shellRemove oil stains, dust, and sweat from hands.

• Key cleaning probeCarefully wipe the spherical or flat surface of the measuring head. If there is stubborn oil stains, you can use a cloth to dip it intraceWipe and immediately wipe dry.

• cleanMeasuring rodandconnecting rod（φ8mm 杆）。

• tool: Clean and softLens clothorDeer skin.

• step：

2. Check and return to position

• Check the probeVisual or tactile inspection of the probe for looseness, wear, or signs of collision.

• Check pointerLightly touch the probe and observe whether the pointer swings smoothly without any jamming, and whether the zeroing is stable.

• Mechanical repositioning: Place the probe infree state(Not under force), if it is a model with a handle, it can be adjustedRotate the measuring rod to a vertical downward directionStore to minimize internal stress.

3. Proper disassembly and storage

• When disassembling from the magnetic watch holder or fixture, firstLoosen the locking nutBe careful to remove it again and do not forcefully pull it out.

• Immediately return the leverage tableOriginal factory specific packaging boxInside. There is usually molded foam in the box, which can provide protection for the gauge head and probe.

• ProhibitMix with other tools such as files and wrenches in the toolbox.

Periodic deep maintenance (monthly or based on usage frequency)

1. Functional Check

• Smooth sliding throughout the entire processUsing fingers with minimal force,Very slowly and uniformlyPush the probe and complete the measurement range. Feeling shouldSmooth as one, without any sense of steps, stuttering or looseness.

• repetition checkFixed on the watch stand, repeat contact measurement 5-10 times on a fixed point, and observe whether the pointer can return to the same position each time (such as zero). Very small deviations (≤ 1/4 of the division value) are allowed, and attention should be paid if the deviation significantly increases.

• Force measurement inspectionCheck if the force is evenly felt and if there are any sudden changes.

2. Deep cleaning (for harsh environments)

• If used frequently in oil and water vapor environments, it can be usedDip a cotton swab in a small amount of alcoholClean the gap around the sliding plunger of the measuring rod to prevent oil sludge accumulation.

• warning：ProhibitDrop or spray alcohol or any liquid directly into the interior of the watch body or dial glass.

Common problem handling and "incurable diseases"

Five major maintenance taboos (prohibited)

1. Overloading/overtraveling is strictly prohibited：

• This is the 'number one killer' of leverage tablesWhen in use,Absolutely not allowedThe measuring head is compressed or stretched to the limit position of the stroke (i.e. the pointer rotates to the hard stops at both ends of the dial). This will instantly cause the internal precision gears to break teeth or the balance spring to deform.

• The correct approachReserve pre pressure during installation (usually 20-30% of the total amount) to ensure that the normal working range is in the middle of the stroke.

2. It is strictly prohibited to drop or impact：

• Any slight fall can lead to irreversible internal injuries. The transmission rod and gear system are very fragile.

3. It is strictly prohibited to soak or use improper cleaning agents：

• Do not immerse the lever gauge in cleaning solution. Do not use strong solvents or lubricants such as gasoline, acetone, WD-40 to clean the exterior, and do not spray them inside.

4. Strictly prohibit measuring rotating workpieces：

• Never use a lever gauge to measure while the workpiece is rotating, as this can easily wear out the measuring head and damage the internal mechanism due to vibration.

5. Self disassembly is strictly prohibited：

• The leverage table isHigh precision sealing body. UserincapableYou should also not attempt to open the back cover or dial. Non professional disassembly will directly result in scrapping and loss of manufacturer's warranty.

Storage and Environmental Requirements

1. environmentConstant temperature, low humidity (moisture-proof cabinet), dust-free, non corrosive gas, and no strong magnetic field (especially for tables with high anti magnetic requirements).

2. posture：place flatSuitable in a dedicated boxPosture. If hanging or standing is required, ensure that the probeFree hanging, not subjected to force.

3. long-term unusedAfter cleaning, apply a thin layer of anti rust oil to the outer surface of the metal, put it in a box, and regularly (such as every quarter) remove it to check its function.

• blow up a balloon

  
  

• alcohol
  

• Dust-free cotton swabs

• high-power flashlight(Used to check for foreign objects inside)

• Special anti rust oil

Suggestion:Consider the lever gauge as a precise 'mechanical watch'. Its value lies in itsAccurate mechanical transmission.Maintenance is the combination of standardized and gentle operating habits, as well as careful care for one minute after each use.A well maintained high-quality lever gauge can accompany you throughout your career.
