Common IMER Combi 250 Replacement Parts

Several components naturally wear over time due to normal operation.

Frequently replaced parts include:

• Diamond blades

• Water pumps

• Drive belts

• Blade guards

• Bearings

• Arbor shafts

• Flanges

• Water hoses

• Water nozzles

• Switches

• Motors

• Table rollers

• Sliding table assemblies

Routine inspection helps identify worn parts before they cause additional damage.

Diamond Blade

The diamond blade is the primary cutting component of the saw.

Blade selection depends on the material being cut.

Common applications include:

• Brick

• Block

• Concrete

• Stone

• Porcelain

• Pavers

• Granite

• Limestone

Important blade specifications include:

• Diameter

• Arbor size

• Maximum RPM

• Bond type

• Wet cutting approval

• Material compatibility

A dull or damaged blade reduces cutting speed and may place additional strain on the motor.

Blade Flanges

Blade flanges secure the diamond blade to the arbor.

Damaged or dirty flanges can cause:

• Blade wobble

• Poor cut quality

• Excess vibration

• Premature blade wear

• Bearing stress

Always inspect flange surfaces before installing a blade.

Replace flanges that show cracking, excessive wear, or distortion.

Arbor Shaft

The arbor shaft supports the blade and transfers power from the motor.

Signs of arbor problems include:

• Blade vibration

• Uneven cutting

• Noise

• Bearing wear

• Difficulty mounting blades

If the arbor becomes bent or damaged, it should be repaired or replaced before continued operation.

Bearings

Bearings allow smooth rotation of the arbor assembly.

Worn bearings may produce:

• Grinding noises

• Vibration

• Heat buildup

• Reduced cutting accuracy

• Rough blade movement

Ignoring worn bearings may damage the shaft and surrounding components.

Drive Belt

The drive belt transfers power from the motor to the blade.

Over time, belts may become:

• Cracked

• Stretched

• Frayed

• Glazed

• Loose

A worn belt may slip during cutting, reducing blade speed and overall performance.

Proper belt tension is important.

An overtightened belt can overload bearings, while a loose belt may slip.

Electric Motor

The electric motor powers the blade.

Common motor-related issues include:

• Failure to start

• Overheating

• Reduced power

• Excessive noise

• Burning odor

• Tripped breakers

Motor problems may result from electrical issues, worn bearings, damaged windings, or excessive cutting loads.

Disconnect power before inspecting electrical components.

Water Pump

The water pump supplies cooling water to the blade.

A functioning pump helps:

• Cool the blade

• Reduce dust

• Improve blade life

• Remove slurry

• Produce cleaner cuts

A failing pump may reduce water flow or stop completely.

Common causes include:

• Debris

• Mineral buildup

• Worn impeller

• Damaged wiring

• Clogged intake

Clean the pump regularly according to the manufacturer's maintenance recommendations.

Water Hoses

Water hoses deliver cooling water from the pump to the blade.

Inspect hoses for:

• Cracks

• Leaks

• Loose fittings

• Blockages

• Kinks

• Wear

Restricted water flow can shorten blade life.

Water Nozzles

Water nozzles direct cooling water onto both sides of the blade.

Blocked nozzles may reduce cooling efficiency.

Clean them regularly to maintain proper water distribution.

Water Tray

The water tray collects cooling water and captures slurry during cutting.

Regular cleaning prevents:

• Pump damage

• Sediment buildup

• Reduced water flow

• Contamination

• Overflow

Allowing excessive slurry to accumulate may shorten pump life.

Sliding Cutting Table

The sliding table supports masonry materials during cutting.

A smooth table allows:

• Straight cuts

• Consistent feed

• Better accuracy

• Reduced operator fatigue

Inspect the table for:

• Damage

• Excessive play

• Bent components

• Rough movement

• Roller wear

A damaged table can reduce cut quality.

Table Rollers

Rollers allow the cutting table to move smoothly.

Worn rollers may cause:

• Jerky movement

• Poor alignment

• Increased effort

• Uneven cuts

Replace worn rollers before they damage guide rails.

Guide Rails

Guide rails keep the cutting table aligned with the blade.

Inspect rails for:

• Damage

• Corrosion

• Bending

• Debris

• Excessive wear

Clean rails regularly to maintain smooth operation.

Blade Guard

The blade guard protects the operator from moving blade components and helps contain water.

Never operate the saw without a properly installed guard.

Inspect the guard for:

• Cracks

• Loose hardware

• Damage

• Missing fasteners

• Bent mounting points

Replace damaged guards immediately.

Splash Guards

Splash guards help contain water and slurry during cutting.

They also improve jobsite cleanliness and reduce operator exposure.

Replace worn or torn splash guards as needed.

Power Switch

The power switch controls motor operation.

Common switch problems include:

• Failure to start

• Intermittent operation

• Loose connections

• Damaged housing

• Sticking contacts

Electrical repairs should follow proper safety procedures.

Disconnect power before servicing.

Power Cord

Inspect the electrical cord regularly.

Replace cords showing:

• Cuts

• Exposed wire

• Burn marks

• Loose plugs

• Damaged insulation

Never operate the saw with a damaged electrical cord.

Wheels and Handles

Portable masonry saws often include transport wheels and carrying handles.

Inspect for:

• Loose hardware

• Cracked wheels

• Bent handles

• Missing fasteners

These parts simplify transportation and improve jobsite safety.

Fasteners

Regular vibration can loosen hardware.

Inspect:

• Bolts

• Nuts

• Washers

• Mounting brackets

• Blade hardware

• Motor fasteners

Tighten according to manufacturer recommendations.

Avoid overtightening.

Routine Maintenance

Preventive maintenance reduces unexpected breakdowns.

A typical maintenance routine includes:

• Cleaning slurry after each use

• Inspecting the blade

• Checking water flow

• Cleaning the water tray

• Inspecting the drive belt

• Examining bearings

• Lubricating approved components

• Tightening hardware

• Inspecting electrical cords

• Cleaning guide rails

Consistent maintenance often extends equipment life.

Cleaning After Every Job

Concrete slurry hardens quickly.

After each use:

• Drain the water tray.

• Remove slurry.

• Clean the pump.

• Flush water lines.

• Wipe guide rails.

• Inspect the blade.

• Dry exposed metal parts.

Clean equipment is easier to inspect and maintain.

Signs Parts Need Replacement

Watch for:

• Reduced cutting speed

• Excessive vibration

• Water leaks

• Motor overheating

• Blade wobble

• Poor water flow

• Grinding noises

• Rough table movement

• Burning smell

• Electrical problems

Addressing small issues early often prevents larger repairs.

Choosing the Correct Replacement Part

Before ordering, verify:

• Model number

• Serial number

• Production year

• Part number

• Component dimensions

• Electrical specifications

• Compatibility

Some components differ between production versions.

Ordering by the official part number helps reduce compatibility problems.

OEM vs Aftermarket Parts

Many owners choose between original equipment manufacturer (OEM) parts and aftermarket replacements.

OEM parts are designed to match the original specifications of the machine.

Aftermarket parts may offer cost savings but can vary in fit, quality, and durability.

When selecting replacement components, verify that they are compatible with your specific IMER Combi 250 model.
