Model G0765 (Mfd. Since 12/13)

WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to avoid accidental slips, which could cause loss of workpiece control.

HAZARDOUS DUST. Dust created while using machinery may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material, and always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

Additional Safety for Metal Lathes

Serious injury or death can occur from getting entangled in, crushed between, or struck by rotating parts on a lathe! Unsecured tools or workpieces attached to rotating objects can also strike nearby operators with deadly force. To minimize the risk of getting hurt or killed, anyone operating this machine MUST completely heed the hazards and warnings below.

CLOTHING, JEWELRY & LONG HAIR. Tie back

long hair, remove jewelry, and do not wear loose clothing or gloves. These can easily get caught on rotating parts and pull you into lathe.

ROTAT ING PARTS. Always keep hands and body at a safe distance from rotating parts—especially those with projecting surfaces. Never hold anything against rotating workpiece, such as emery cloth, that can pull you into lathe.

GUARDING. Guards and covers protect against entanglement or flying objects. Always ensure they are properly installed while machine is running.

ADJUSTMENT TOOLS. Remove all chuck keys, wrenches, and adjustment tools before turning lathe ON. A tool left on the lathe can become a deadly projectile when spindle is started.

SAFE CLEARANCES. Before starting spindle, verify workpiece has adequate clearance by handrotating it through its entire range of motion.

NEW SETUPS. Test each new setup by starting spindle rotation at the lowest speed and standing to the side of the lathe until workpiece reaches full speed and you can verify safe rotation.

SPINDLE SPEEDS. Using spindle speeds that are too fast for the workpiece or clamping equipment can cause rotating parts to come loose and strike nearby people with deadly force. Always use slow spindle speeds with large or non-concentric workpieces. Never exceed rated RPM of the chuck.

CHUCKS. Chucks can be heavy and difficult to hold. During installation and removal, protect your hands and precision bed ways by using a chuck cradle or piece of plywood over the bed ways. Use lifting equipment, as necessary, for large chucks.

LONG STOCK SAFETY. Long stock can whip violently if not properly supported. Always support any stock that extends from the chuck/headstock more than three times its own diameter.

CLEARING CHIPS. Metal chips can be razor sharp. Avoid clearing them by hand or with a rag. Use a brush or vacuum instead.

SECURE WORKPIECE. An improperly secured workpiece can fly off spindle with deadly force. Make sure workpiece is properly secured before starting the lathe.

STOPPING SPINDLE. Always allow spindle to completely stop on its own, or use a brake, if provided. Never put hands or another object on a spinning workpiece to make it stop faster.

CRASHING. A serious explosion of metal parts can occur if cutting tool or other lathe component hits rotating chuck or a projecting part of workpiece. Resulting metal fragments can strike nearby people and lathe will be seriously damaged. To reduce risk of crashing, ALWAYS release automatic feeds after use, NEVER leave lathe unattended, and CHECK all clearances before starting lathe.

TOOL SELECTION. Cutting with incorrect or dull tooling increases risk of injury from broken or dislodged components, or as a result of extra force required for operation. Always use sharp tooling that is right for the job.

SANDING/POLISHING. To reduce risk of entanglement, never wrap emery cloth around rotating workpiece. Instead, use emery cloth with the aid of a tool or backing board.

MEASURING WORKPIECE. To reduce risk of entanglement, never measure rotating workpieces.

-12-

Model G0765 (Mfd. Since 12/13)

Additional Chuck Safety

ENTANGLEMENT. Entanglement with a rotat-

ing chuck can lead to death, amputation, broken bones, or other serious injury. Never attempt to slow or stop the lathe chuck by hand, and always roll up long sleeves, tie back long hair, and remove any jewelry or loose apparel BEFORE operating.

CHUCK SPEED RATING. Excessive spindle speeds greatly increase the risk of the workpiece or chuck being thrown from the machine with deadly force. Never use spindle speeds faster than the chuck RPM rating or the safe limits of your workpiece.

USING CORRECT EQUIPMENT. Many workpieces can only be safely turned in a lathe if additional support equipment, such as a tailstock or steady/ follow rest, is used. If the operation is too hazardous to be completed with the lathe or existing equipment, the operator must have enough experience to know when to use a different machine or find a safer way.

TRAINED OPERATORS ONLY. Using a chuck incorrectly can result in workpieces coming loose at high speeds and striking the operator or bystanders with deadly force. To reduce the risk of this hazard, read and understand this document and seek additional training from an experienced chuck user before using a chuck.

CHUCK CAPACITY. Avoid exceeding the capacity of the chuck by clamping an oversized workpiece. If the workpiece is too large to safely clamp with the chuck, use a faceplate or a larger chuck if possible. Otherwise, the workpiece could be thrown from the lathe during operation, resulting in serious impact injury or death.

CLAMPING FORCE. Inadequate clamping force can lead to the workpiece being thrown from the chuck and striking the operator or bystanders. Maximum clamping force is achieved when the chuck is properly maintained and lubricated, all jaws are fully engaged with the workpiece, and the maximum chuck clamping diameter is not exceeded.

PROPER MAINTENANCE. All chucks must be properly maintained and lubricated to achieve maximum clamping force and withstand the rigors of centrifugal force. To reduce the risk of a thrown workpiece, follow all maintenance intervals and instructions in this document.

DISCONNECT POWER. Serious entanglement or impact injuries could occur if the lathe is started while you are adjusting, servicing, or installing the chuck. Always disconnect the lathe from power before performing these procedures.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrican or qualified service personnel in accordance with all applicable codes and standards.

Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

For your own safety and protection of

Note: The circuit requirements listed in this man-

ual apply to a dedicated circuit—where only one machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure that the circuit is properly sized for safe operation.

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine.

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

We do not recommend using an extension cord with this machine. cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following requirements:

Site Considerations

Weight Load

Physical Environment

Place this machine near an existing power source.

Shadows, glare, or strobe effects that may distract

Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual.

See below for required space allocation.

Children or untrained people may be seriously injured by this machine. Only install in an access restricted location.

The physical environment where the machine is operated is important for safe operation and longevity of machine components. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 41°–104°F; the relative humidity range exceeds 20–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps.

Electrical Installation

Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave access to a means of disconnecting the power source or engaging a lockout/tagout device, if required.

Tailstock

The tailstock is typically used to support long workpieces at the side opposite the spindle, using a live or dead center. It can also hold a tapered drill bit (or a drill chuck with a regular drill bit) for boring holes. Unlike boring done with a drill press where the workpiece is fixed and the drill bit rotates, the drill bit in a tailstock remains stationary while the workpiece is rotated by the spindle.

The entire tailstock can be repositioned and locked in place along the length of the bed. An independently controlled offset adjustment allows the upper part of the tailstock to move perpendicular to the bedways so it can be aligned with the spindle center (for concentric turning) or offset from the spindle center (for tapered turning).

The tailstock quill also features independent adjustment controls that allow it to be advanced toward the spindle or locked firmly in position.

Installing Tooling

Note: If the tooling has an open hole in the end,

then a screw can be threaded into the end of the tool to provide a solid surface for the quill pin to push against when the quill is retracted for tool removal. Otherwise, removal of such tooling may be difficult.

The tailstock quill can be offset from the spindle centerline for turning tapers. Offsetting quill toward the front of the lathe results in a taper at the tailstock end. Conversely, offsetting quill toward the back of the lathe results in a taper at the spindle end.

Note: The marks on the offset indicator are arbitrary. For a precise offset, use a dial indicator to check quill movement while adjusting the screws.

This is an essential adjustment that should be verified or performed each time the tailstock is used to turn concentric workpieces between centers or immediately after offsetting the tailstock when turning a taper. If the tailstock is not aligned with the spindle centerline when it is supposed to be, turning results will be inaccurate along the length of the workpiece.

Dead Centers

Dead centers are one-piece high-speed steel centers that require low spindle speeds and a small amount of oil to reduce friction heat that may damage the workpiece.

Mount the MT#2 dead center (see Figure 36) in the tailstock. Since the workpiece will rotate against the center and generate friction, the tip of the center must be lubricated to avoid premature wear and maximize smooth operation.

2. Thoroughly clean and dry all mating surfaces of spindle bore and center, making sure that no lint or oil remains on these surfaces.

3. Mount chuck or faceplate onto spindle, whichever is correct for your operation.

4. Insert MT#3 center into spindle bore through chuck or faceplate.

Below is an example photo of a dead center

installed in spindle, using a lathe dog and faceplate for turning between centers.

Using the correct spindle speed is important for getting safe and satisfactory results, as well as maximizing tool life.

To set the spindle speed for your operation, you will need to: 1) Determine the best spindle speed for the cutting task, and 2) configure the lathe controls to produce the required spindle speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed to use for any given operation, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the workpiece, as noted in the formula shown below.

*Recommended

Cutting Speed (FPM) x 12

Dia. of Cut (in inches) x 3.14

Spindle

Speed

(RPM)

*Double if using carbide cutting tool

Figure 46. Spindle speed formula for lathes.

Cutting speed, typically defined in feet per minute (FPM), is the speed at which the edge of a tool moves across the material surface.

A recommended cutting speed is an ideal speed for cutting a type of material in order to produce the desired finish and optimize tool life.

Use this handwheel to move the tool toward and away from the work. The cross slide handwheel has an indirect-read graduated dial. This means the distance shown on the scale represents the actual distance the tool moves.

Compound Rest Handwheel

Graduated Dial

Increments .............................. 0.001" (0.025mm)

Use this handwheel to move the cutting tool linearly along the set angle of the compound rest. Set the compound rest angle by hand-rotating it and securing in place with two cap screws. The compound rest has an indirect-read graduated dial.

Model G0765 (Mfd. Since 12/13)

The books Machinery’s Handbook or Machine Shop Practice, and some internet sites, pro-

vide excellent recommendations for which cutting speeds to use when calculating the spindle speed. These sources also provide a wealth of additional information about the variables that affect cutting speed and they are a good educational resource.

Also, there are a large number of easy-to-use spindle speed calculators that can be found on the internet. These sources will help you take into account the applicable variables in order to determine the best spindle speed for the operation.

-39-

Setting Spindle Speed Range

The high/low range lever shown in Figure 47, is used to select one of the two spindle speed ranges.

Configuration Example

Follow this example to gain a better understanding of how to set the spindle speed.

To set spindle speed to 100 RPM:

High/Low

Range Lever

Figure 47. High/low range lever set to low.

When the lever is moved to the right, as shown in Figure 47, the low spindle speed range (100–1000 RPM) is selected. When the lever is moved to the left, the high spindle speed range (100–2000) RPM is selected.

Setting Spindle Direction & Speed

Set the spindle rotation direction to forward or reverse with the spindle direction switch, shown in Figure 48. Reset the Emergency Stop button, press the ON button, then turn the variable speed dial clockwise until the desired spindle speed displays on the spindle speed display.

1. Make sure spindle is completely stopped, and shift high/low range lever to LOW, as shown in Figure 47.

Note: If high/low range lever does not eas-

ily adjust into position, rotate chuck by hand while you apply pressure to lever. When gears align, the lever will easily move into place.

2. Turn variable speed dial to "0".

3. Turn spindle direction switch to "F", and

press ON button.

4. Adjust variable speed dial until spindle speed display reads 100 RPM.

Power Feed

The carriage has power feed options for either threading or non-threading operations. However, this subsection only covers using the power feed option for non-threading operations. To learn how to power the carriage for threading operations, refer to Threading on Page 46.

To avoid damaging lathe, ALWAYS make sure spindle is completely stopped BEFORE using headstock controls to make changes.

Power Feed Controls

Use the following descriptions and figures to understand the power feed controls.

Before using power feed, you may have to reconfigure the end gears, depending on how they are set up. The lathe comes from the factory with the end gears setup in the standard configuration (refer to End Gears on Page 43). This end gear configuration achieves a fixed feed rate of 0.04 in/ rev. Refer to End Gears on Page 43 for detailed instructions on how to configure the end gears.

B. Feed Direction Lever: Selects carriage trav-

el direction. The carriage moves left when feed direction lever is up, half nut lever is engaged, and spindle switch is set to "F".

The carriage moves right when the feed

direction lever is all the way down. The carriage will not move when the lever is in the center position.

Carriage travel direction reverses when the

spindle switch is set to "R".

SECTION 6: MAINTENANCE

Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.

Schedule

Ongoing

To maintain a low risk of injury and proper machine operation, if you ever observe any of the items below, shut down the machine immediately and fix the problem before continuing operations:

• Loose mounting bolts or fasteners.

• Worn, frayed, cracked, or damaged wires.

• Guards or covers removed.

• Emergency Stop button not working correctly.

• Damaged or malfunctioning components.

Daily, Before Operations

• Add oil to the ball oilers (Page 51).

• Lubricate the leadscrew and carriage rack (Page 52).

• Lubricate the bedways (Page 52).

• Clean/lubricate the cross slide and compound slide (Page 52).

• Disengage the half nut on the carriage (to prevent crashes upon startup).

Daily, After Operations

• Press the Emergency Stop button (to prevent accidental startup).

• Vacuum/clean all chips and swarf from bed, slides.

• Wipe down all unpainted or machined surfaces with an oiled rag.

Annually

• Lubricate change gear bushing and tumbler gears (Page 53).

Cleaning/Protecting

Because of its importance, we recommend that the cleaning routine be planned into the workflow schedule.

Typically, the easiest way to clean swarf from the machine is to use a wet/dry shop vacuum that is dedicated for this purpose. The small chips left over after vacuuming can be wiped up with a slightly oiled rag. Avoid using compressed air to blow off chips, as this may drive them deeper into the moving surfaces or cause sharp chips to fly into your face or hands.

All unpainted and machined surfaces should be wiped down daily to keep them rust free and in top condition. This includes any surface that is vulnerable to rust if left unprotected. Use a quality ISO 68 way oil (see Page 49 for offerings from Grizzly) to prevent corrosion.

Ball Oilers

Oil Type ..............................ISO 32 or Equivalent

Amount ..................................... 1 or 2 Squirts/Fill

Lubrication Frequency ................................. Daily

This lathe has four ball oilers that should be oiled on a daily basis before beginning operation.

Proper lubrication of ball oilers is done with a pump-type oil can that has a plastic or rubberized cone tip. We do not recommend using metal needle or lance tips, as they can push the ball too far into the oiler, break the spring seat, and lodge the ball in the oil galley.

Lubricate the ball oilers before and after machine use, and more frequently under heavy use. When lubricating ball oilers, first clean the outside surface to remove any dust or grime. Push the tip of the oil can nozzle against the ball oiler to create a hydraulic seal, then pump the oil can once or twice. If you see sludge and contaminants coming out of the lubrication area, keep pumping the oil can until the oil runs clear. When finished, wipe away any excess oil.

Refer to Figure 75 to identify the location of each ball oiler.

NOTICE

The recommended lubrication is based on light-to-medium usage. Keeping in mind that lubrication helps to protect the value and operation of the lathe, these lubrication tasks may need to be performed more frequently than recommended here, depending on usage.

Failure to follow reasonable lubrication practices as instructed in this manual could lead to premature failure of lathe components and will void the warranty.

Machine Storage

Preparing Lathe for Storage

1. DISCONNECT LATHE FROM POWER!

2. Thoroughly clean all unpainted, bare metal

surfaces, then apply a liberal coat of way oil, heavy grease, or rust preventative. Take care to ensure these surfaces are completely covered but that the rust preventative or grease is kept off of painted surfaces.

3. Lubricate machine as outlined in lubrication section. Be sure to use an oil can to purge all ball oilers and oil passages with fresh oil.

4. Place a few moisture absorbing desiccant packs inside of the electrical box.

5. Cover lathe and place it in a dry area that is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint.

Remove the end cover and B/C change gear, clean the shaft and keyed bushing with mineral spirits and dry. Apply a thin coat of white lithium grease to the inside of the bushing shaft, then reinstall it.

Backlash Adjustment

Backlash is the amount of free play felt while changing rotation directions with the handwheel. This can be adjusted on the cross slide leadscrew. Before beginning any adjustment, make sure all associated components are cleaned and lubricated and locks are loose.

Angle the compound rest so you can access the cap screws shown in Figure 80. Loosen the outer cap screws, adjust the inner cap screw, then tighten the outer cap screws. Move the cross slide handwheel back and forth and adjust backlash until it is approximately 0.002"–0.003", as indicated on the graduated dial. Re-adjust the compound rest angle when you are finished.

When adjusting backlash, tighten the components enough to remove backlash, but not so much that the components bind the leadscrew, making it hard to turn. Overtightening will cause excessive wear to the sliding block and leadscrew.

Reducing backlash to less than 0.002" is impractical and can lead to accelerated wear in the leadscrew and other components. Avoid the temptation to overtighten the backlash nut or screw while adjusting.

Cross Slide

Tools Needed: Qty

Hex Wrench 2.5mm ........................................... 1

Hex Wrench 3mm ............................................. 1

The cross slide backlash is adjusted by tightening and loosening the inner and outer cap screws shown in Figure 80. The inner screw adjusts the height of the leadscrew nut, taking up lash between the nut and leadscrew.

Leadscrew End-Play

Adjustment

After a long period of time, you may find that the leadscrew develops excessive end-play or lateral movement. This lathe is designed so that endplay can be removed with a simple adjustment.

Tools Needed Qty

Model G0765 (Mfd. Since 12/13)

Gib Adjustment

The goal of adjusting the gib screws is to remove sloppiness or "play" from the ways without overadjusting them to the point where they become stiff and difficult to move.

In general, loose gibs cause poor finishes and tool chatter; however, over-tightened gibs cause premature wear and make it difficult to turn the handwheels.

Compound Slide

Adjustment

Fasteners

Figure 83. Compound slide gib adjustment hex

nuts and cap screws.

The gib adjustment process usually requires some trial-and-error. Repeat the process as necessary until you find the best balance between loose and stiff movement. Most machinists find that the ideal gib adjustment is one where a small amount of drag or resistance is present, yet the handwheels are still somewhat easy to move.

Clean and lubricate the ways before beginning any adjustments. Refer to Lubrication on Page

51 for instructions and lubricant specifications.

Tools Needed Qty

Open-End Wrench 7mm .................................... 1

Hex Wrench 3mm .............................................. 1

To adjust cross slide and compound slide gibs:

1. DISCONNECT LATHE FROM POWER!

2. Loosen three hex nuts on side of cross slide or compound slide (see Figures 82–83).

3. Adjust all three cap screws in small and equal

increments, then test movement of slide by rotating handwheel.

Note: Turning cap screws clockwise tightens

the gib, and turning them counterclockwise loosens the gib.

4. When satisfied with gib adjustment, use hex wrench to prevent cap screws from moving, then retighten hex nuts to secure the settings.

5. Recheck movement of slide and, if necessary, repeat Steps 2–4.

Half Nut Adjustment Fuse Replacement

The rigidity of the half nut engagement is adjusted by tightening or loosening the half nut gib screws. Adjust the half nut if it feels too loose or too tight when being engaged. Movement that is too stiff will accelerate wear. Movement that is too sloppy will produce inaccurate turning or threading results.

Tool Needed Qty

Hex Wrench 2mm .............................................. 1

To adjust half nut:

1. DISCONNECT LATHE FROM POWER!

2. Disengage half nut.

3. Adjust gib set screws (see Figure 84) in

small, even increments so one end of gib does not become tighter than the other.

This lathe features an on-board fuse designed to blow to protect sensitive electrical parts from thermal damage in the event of an overload. If the spindle does not start, replace the fuse.

Replacement fuse part number: P0765166.

To replace fuse:

1. DISCONNECT LATHE FROM POWER!

2. Unthread fuse holder by rotating counter-

clockwise (see Figure 85) and remove fuse.

Brush Replacement

This lathe is equipped with a universal motor that uses two carbon brushes to transmit electrical current inside the motor. These brushes are considered to be regular "wear items" or "consumables" that will need to be replaced during the life of the motor. The frequency of required replacement is often related to how much the motor is used and how hard it is pushed.

3. Unscrew rear brush cap and carefully remove brush from motor (see Figure 87).

Timing Belt Tension

& Replacement

The timing belt transfers power from the motor to the drive pulley (see Figure 89).

Because the molded teeth in the belt fit together with matching teeth in the pulley, the timing belt will not slip unless the belt teeth become overly worn or belt tension is overly loose.

An improperly tensioned timing belt will slip, which quickly causes it to become damaged and unsuitable for further use. Therefore, it is essential to maintain belt tension properly to prevent slippage.

Once a timing belt begins to slip, it must be replaced in order to regain proper power transmission.
