The CRAFCO Model 30 Pavement Router was designed specifically to widen and clean joints and
cracks in asphalt and concrete surfaces. The Crafco Model 30 Pavement Router is NOT intended to
be used to clean old sealant from joints and cracks.
The CRAFCO Model 30 Pavement Dust Control Router is a self-contained unit; no external power
source is needed to operate the dust collection system. It was designed to reduce the amount of
fugitive dust particles being introduced into the air when widening and cleaning joints and cracks in
asphalt surfaces. The CRAFCO Model 30 Pavement Dust Control Router was not intended to pick
up all dirt and debris from the joint or crack after routing.
The CRAFCO Model 30 Pavement Self-Propelled Router is a self-contained unit; no external power
source is needed to operate the drive system. It was designed to reduce worker fatigue from
moving from one distressed area to another. The Crafco Model 30 Pavement Self-Propelled Router
was not intended to drive forwards and route cracks at the same time. The handle bar has two
separate drive handles, standing at the operators position the drive handle on the left works the
electric clutch and the drive handle on the right works the drive wheels.
The CRAFCO Crack Saw Attachment is designed to offer a secondary use for our Model 30
Pavement Router. This tool will allow the transformation of the standard Model 30 to a random
crack saw for use on concrete or asphalt pavement in less than 1 hour. Diamond or abrasive blade
(not included) may be used wet or dry on the Model 30. Crafco part number 31350, Random Crack
Saw Cutting Kit, may be ordered for the Model 30 Router with the initial order, or as an add on kit.
The kit includes all parts necessary to transform a Crafco Model 30 Pavement Router into a saw.

obstructed.
Check that the air cleaner components and all shrouds, equipment covers, and guards
are in place and securely fastened.
Check and/or open the fuel valve on the bottom of the fuel tank so that the engine will
get fuel.
The safe operation of this machine is the operator’s responsibility.
Use extreme care when operating this machine; safety is the result of being careful
and paying attention to details.
Always put on protective clothing, long pants, gloves, hard-soled shoes, safety
glasses, dust mask, and ear protection. Tighten all bolts, nuts, and screws every 100
hours.
It is recommended that you read the Engine Operators Manual before starting the engine.
StepAction
To start engine, place the throttle control midway in the “slow” position, and place the
1
2
choke control into the “on” position.
Note:With non-electric clutch you must pull and hold the engine stop switch at the
operator’s position for the engine to start and run.
Start the engine by activating the key switch. Release the switch as soon as the
engine starts.
Note: Do not crank the engine continuously for more than 10 seconds at a time. If the
engine does not start, allow a 60 second cool down period between starting attempts.
Failure to follow these guidelines can burn out the starter motor.
Note: Upon start-up a metallic ticking may occur. This is caused by the hydraulic
lifter leakdown during storage. Run the engine for 5 minutes. The noise will normally
cease in the first minute. If noise continues, run the engine at mid throttle for 20
minutes. If noise persists, take the engine to your local Kohler Service Engine Dealer.
Note: If the engine develops sufficient speed to disengage the starter, but does not
keep running (a false start), the engine rotation must be allowed to come to a
complete stop before attempting to restart the engine. If the starter is engaged while
the flywheel is rotating, the starter pinion and flywheel ring gear may clash, resulting in
damage to the starter.
If the starter does not turn the engine over, shut off starter immediately. Do not make
further attempts to start the engine until the condition is corrected. Do not start using
another battery. See your Kohler Engine Service Dealer for trouble analysis.
For a Cold Engine: Gradually return the choke control to the “off” position after the

engine starts and warms up. The engine/equipment may be operated during the
warm-up per iod, but it may be necessary to leave the choke partially on until the
engine warms up.
Black smoke from the exhaust and a rough running engine usually indicate overchoking.
1 Be sure to use the proper engine oil for the temperature expected. See Engine Operators
Manual for recommended SAE Viscosity Grades.
2 Set speed control at part throttle position.
3 A warm battery has much more starting capacity than a cold battery.
4 Use fresh winter grade fuel.
Winter grade gasoline has a higher volatility to improve starting. Do not use gasoline
leftover from summer.
5.4 Battery
A 12 volt battery is used. If the battery charge is not sufficient to crank the engine, recharge the
battery. See Section 6.3.1 f or battery charging instructions.
5.5 Stopping the Engine
Step Action
1 Place the throttle control midway between the “slow” and “fast” positions.
2 Allow the engine to run a minimum of 15 seconds.
3 Stop the engine by turning off the key switch.

5.6 Operation Guidelines
Follow these guidelines to ensure proper operation of your CRAFCO Model 30 Pavement Router.
The engine will operate continuously at angles up to 25 degrees. Check oil level to assure
crankcase oil level is at the “F” mark on the dipstick. Do not operate the engine continuously at
angles exceeding 25 degrees in any direction. Engine damage could result from insufficient
lubrication.
If not using the router for longer periods, turn off the fuel valve under the fuel tank
and cooling areas can cause extensive damage due to overheating.
Operating Instructions
Cooling 5.6.2
Hot Parts!
Engine components can get extremely hot from operation. To prevent severe burns,
do not touch these areas when the engine is running or immediately after it is turned
off. Never operate the engine with heat shields or guards removed.
Note: If debris builds up on the screen or other cooling air intake areas, stop the
engine immediately and clean. Operating the engine with blocked or dirty air intake
Engine Speed 5.6.3
The high idle speed for this engine is 3750 RPM, no load.
WARNING
CAUTION
Do not tamper with the governor setting or increase the maximum engine speed. Overspeed is
hazardous, may hinder cutter action, and will void the warranty.
Engine exhaust gases contain poisonous carbon monoxide. Carbon monoxide is
odorless, colorless, and can cause death if inhaled. Avoid inhaling exhaust fumes, and
never run the engine in a closed building or confined area.
For Model 30 Pavement Dust Control Router, follow these procedures to attach all dust control
mechanisms before starting or operating the machine.
StepAction
To make attaching the cutter head dust shroud more accessible, raise the front of the

Remove cutter head dust shroud from the storage bracket and bring around to front of
router.
Bring the shroud up from the bottom of the housing and align the pin hole with the slots in
the mounting brackets.
Use the Brush Manipulation Tool to push the Seal Brushes on both sides of shroud up
above the cutter housing. The brushes should be in an upward position. See Figure 5.2
Lower the router back onto its wheels.
Make sure the large particle dust collection bin is empty and is securely attached to
mounting bracket before beginning your routing operation.
Make sure the dust collection bag is clean and securely clamped to filter mounting bracket
with adjustable quick release gear clamp. The quick release gear clamp is adjustable and
should be adjusted so that it holds the dust collection bag securely in place. Do not overtighten the clamp as this may damage the dust collection bag. The support rod was
designed so it could be slid into a rearward position for transportation of router where
space is limited. The support rod should be fully extended in its forward position before
routing begins.
Raise the cutter mechanism by pushing the rocker switch to the up position.
Once your machine is ready to begin operation, start the engine as in Table 5-2 Engine Starting
Instructions, and then use these instructions to begin cleaning joints and cracks.

The stabilizer mechanism is designed to stabilize the machine and to act as a brake.
WARNING
The CRAFCO Model 30 Pavement Router pushes toward the operator when routing. Tightly
compacted surfaces, deep or wide cuts, or hard aggregate may cause sudden machine
movement toward operator. This “kickback” could cause the operator to lose balance or control
of the machine resulting in serious personal injury. When operating, keep wear plate in contact
with pavement and hold handle with both hands. For Emergency Stop, push down firmly on
machine handle or release safety “Clutch” handle, which disengages the electric clutch. Push
machine handle away.
Lower cutter head, using Actuator switch (Figure 5.4), until cutters slightly touch the
surface.
Notice shade and number on the depth indicator (Figure 5.3). Each shade represents
approximately 1/4 inch (6.35 mm) depth variation.
Do not try to go too fast. Do not overload the engine. Overloading the engine will slow
cutting action and cause damage to engine and drive components. A bouncing or
hammering action usually indicates the machine is moving too fast or the cutters have
worn out of round (refer to troubleshooting on page 8-1).
Let the machine thoroughly clean the joint. For deep cuts (deeper than 3/4 inch (19
mm)) it may be necessary to make two passes.
A stabilizer mechanism (Figure 5.5) is used on the Crafco Pavement Router to
improve the stability of the machine and to act as a brake.
TO SLOW OR STOP THE ROUTER, simply push down on the handle or release
safety “clutch” handle which disengages the electric clutch.
For normal operation, let skid plate drag on paved surface while machine is in
operation.
Skid plate (Part No. 20919) should be replaced before wear reaches the vertical leg of
the bent angle.
As cutters wear, depth of cut will change. To compensate for cutter wear, repeat step
#7 as often as necessary to reset depth.
The following applies the Router’s with the Dust Control Router. As you begin to route, the dust that
is sucked up from the cutter head shroud enters the cyclone where a majority of the debris is spun
out of the air stream and deposited in the large particle dust collection bin. The amount of time or
distance that can be routed before the large particle dust collection bin will need to be emptied will
vary depending on the condition of the asphalt, approximately 500 to 1000 feet (150 to 300 meters).
If you have ordered the Dust Control Retrofit Kit (PN 31550K) please see the separate installation
instructions provided.
StepAction
Never operate the unit without all the dust control components attached, in particular
the cutter head dust shroud. This could cause injury or damage from flying debris.
1 When beginning a routing operation, check the large particle dust collection bin
frequently to gauge t he distance that can be routed before empting the large particle
dust collection bin. The large particle dust collection bin should be emptied at
approximately 3/4 to 7/8 full.
If the large particle dust collection bin becomes overfilled the debris will be sucked up
through the cyclone and deposited in the dust collection bag, reducing the run time of
the dust collection bag.
2 To empty the large particle dust collection bin, reduce engine speed to idle.
3 Support the bottom of the large particle dust collection bin with one hand, keeping the
bin pressed up firmly against the mounting bracket.
4 With your other hand, unlatch the rubber latches on the large particle dust collection
bin.
The large particle dust collection bin weighs approximately 30 lbs. when full
WARNING
CAUTION
CAUTION
5 Dump the large particle dust collection bin in a larger receptacle where it can be
disposed of properly at a later time.
6 Reattach the large particle dust collection bin to the mounting bracket.
7 Lightly tap sides of the dust collection bag with your hands.
Note:
dust collection bag. This dust forms a “Dust Cake” on the inside wall of the dust
collection bag and will restrict the amount of air that can escape through the dust
collection bag, reducing the overall suction of the system. Tapping on the side of the
dust collection bag will knock this dust cake loose from the sides of the dust collection
bag, increasing the amount of time that can be routed before the dust collection bag
will need to be serviced. (see Section 6.11)
8 Return engine to high speed and continue routing.
During router operation, what dust isn’t spun out by the cyclone, enters the

9 At the end of the day remove the cutter head dust shroud and store on the Shroud
Storage Bracket located on top of the cyclone.
WARNING
DO NOT leave the router resting on the seal brushes as they will deform. Excessive
deformation of the seal brushes will hinder the shrouds ability to trap dust behind the
shroud, reducing the efficiency of the dust collector.
Moving the Self Propelled Router 5.8.2
Use the self-propelled function only for ease of moving the router from one distressed area to
another.
StepAction
1 Reduce engine speed to idle

Operating Instructions
5.9 Saw Cut Attachment
The Crafco Random Crack Saw Attachment is designed to offer a secondary use for our Model 30
Pavement Router. This tool will allow the transformation of the standard Model 30 Pavement Router
to a random crack saw for use on concrete or asphalt pavement in less than 1 hour. The Saw Cut
Attachment may also be used on a Dust Control Router, though the dust control feature does not
work with the saw cut attachment. Ask your Crafco customer service representative for Part
Number 31350. This kit includes all parts necessary to transform a Crafco Model 30 Pavement
Router into a saw.
Diamond or abrasive blade (not included) may be used wet or dry. Contact your local concrete or
pavement supply store for saw blades.
Operate the Model 30 Router with the Saw Cut Attachment in the same way as described in
Sections 5.2, and 5.8. To perform wet cuts, attach a hose to the hose connector, turn on water
supply, and open the ball valve. Then cut as normal.
CAUTION
same direction as the router cutters. It is important to make sure that the saw blade is oriented in the
correct direction to cut while the machine moves backwards.
The Saw Cut Attachment may be installed by Crafco at the Chandler AZ manufacturing plant, or
installed by the operator. If you choose to install it yourself follow the instructions in Table 5-10,
Table 5-11, and Table 5-12.
Turn the key to the on position, use the up/down toggle switch to lower the cutter head
until it is resting on the ground then turn the key back to the off position.
Remove power from unit by disconnecting negative battery cable to prevent accidental
startup.
Remove 4 bolts holding the belt guard in place and set belt guard aside.
Back off belt tension by backing off adjusting nuts on belt adjuster located under the
engine mounting channel. Remove the belts and retain for later use. (If belts are showing
signs of wear, replace with a new set of belts).
Remove the top 3 bolts in each of the two main shaft bearings.
It is not necessary to remove the bottom bolt from the main shaft bearings, they can be left
intact. This will retain the filler plates. It is also not necessary to remove or loosen the set
screws holding the bearings to the main shaft, nor is it necessary to remove the belt
sheave.
Once the 6 main shaft bearing bolts have been completely removed, slowly lift up on the
handle to raise the back of the router. Do not raise the cutter head assembly more than a
½” off of the ground without verifying that the cutter head assembly has broken free of the
housing and will easily slid out. This will prevent the cutter head assembly from having a
“long fall” to the ground, preventing damage to the cutters or the cutter head itself.
If the cutter head fails to immediately slide out of the housing lower the handle back down
to the ground. Loosen the set screws on one shaft bearing only. Leaving one bearing in
place will help with realignment if you were to choose to reinstall the cutter assembly at a
later time. If necessary, lightly tap on the end of the main shaft to free the cutter head
assembly from the housing.
Once the cutter head assembly has broken free of the housing, slowly lift the handle up
until the cutter head assembly is clear of the housing and the router is resting on the front
support strip. The cutter head can now be rolled out from underneath of the router and
stored until needed.

Follow these instructions when storing the CRAFCO Model 30 Pavement Router
CRAFCO Model 30 Dust Control Router 5.10.1
DO NOT leave the machine resting on the seal brushes or the brushes will become deformed,
causing them not to function properly. The dust collection bag should be stored in a covered area
out of direct sunlight and away from moisture. Store the dust collection bag in a place where it won’t
be inadvertently torn or damaged.
CRAFCO Model 30 Pavement Router and Self-Propelled Router (without dust control) 5.10.2
DO NOT rest the weight of the machine on the rubber rock deflector or rubber will become
deformed, causing them not to function properly. Store the machine with engine in a near level
position.
This chapter contains all normal maintenance instructions to properly maintain your machine.
6.1 Oil Recommendations
Using the proper type and weight of oil in the crankcase is extremely important. Failure to use the
correct oil, or using dirty oil, causes premature engine wear and failure. Check engine oil daily.
Change oil after every 100 hours of operation. Change oil filter every 200 hours. Use Crafco part
number 31330. Refer to engine owner’s manual for more information.
Oil type 6.1.1
Use high quality detergent oil of API (American Petroleum Institute) service class SG or SH. Select
the viscosity based on the air temperature at the time of operation as shown in Figure 6.1.
Note:Using oil other than service class SG or SH or extending oil change intervals longer than
recommended can cause engine damage. Refer to the engine owner’s manual for detailed oil check,
oil change, and oil filter change procedures and intervals.
Explosive Fuel!
Gasoline is extremely flammable and its vapors can explode if ignited. Store gasoline only in approved
containers, in well ventilated, unoccupied buildings away from sparks or flames. Do not fill the fuel tank
while the engine is hot or running since spilled fuel could ig n ite if it comes in contact with hot parts or
sparks from ignition. Do not start the engine near spilled fuel. Never use gasoline as a cleaning agent.
General Recommendations 6.2.1
Purchase gasoline in small quantities and store in clean, approved containers. A container with a
capacity of 2 gallons or less with a pouring spout is recommended. Such a container is easier to
handle and helps eliminate spillage during refueling.
To minimize gum deposits in your fuel system and to insure easy starting, do not use gasoline left
over from the previous season.
Do not add oil to the gasoline.
Do not over-fill the fuel tank. Leave room for the fuel to expand.
Fuel Type 6.2.2
For best results use only clean, fresh, unleaded gasoline with a pump sticker octane rating of 87 or
higher. In countries using the Research method, it should be 90 octane minimum.
Unleaded gasoline is recommended as it leaves less combustion chamber deposits. Leaded
gasoline may be used in areas where unleaded is not available and exhaust emissions are not
regulated. Be aware, however, that the cylinder heads may require more frequent service.
Gasoline/Alcohol Blends 6.2.3
Gasoline (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is approved as a fuel for
Kohler engines. Other gasoline/alcohol blends are not approved.
Gasoline/Ether Blends 6.2.4
Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to maximum of
15% MTBE by volume) are approved as a fuel for Kohler engines. Other gasoline/ether blends are
Check charge condition. Keep battery connections tight and clean. Check the fluid level in battery
regularly.
Battery Recharging 6.3.1
When recharging, do not use a battery charger rated for more than 8 AMP’s. If the battery has fallen
below 10.5 volts, a charger made specifically for charging AGM batteries is required. Do not
overcharge the battery.
WARNING
Explosive Gas!
Batteries produce explosive hydrogen gas while being charged. To prevent a fire or explosion, charge
batteries only in well ventilated areas. Keep sparks, open flames, and other sources of ignition away
from the battery at all times. Keep batteries out of the reach of children. Remove all jewelry when
servicing battery.
6.4 Periodic Maintenance
Follow a regular schedule of inspection and servicing, based on operating hours. Keep an accurate
logbook of maintenance, servicing, and operating time. Use the factory recommended Periodic
Maintenance Schedule (based on favorable operating conditions) to serve as a guide to get long
and efficient engine life.
For severe duty, extreme temperature, etc., service more frequently. Neglecting routine
maintenance can result in engine failure or permanent damage.
For any abnormalities in operation, unusual noises from the engine or accessories, loss of power,
overheating, etc., contact your nearest Kohler Service Center.
Periodically inspect the in-line fuel filter and replace when dirty using Crafco part number 31331.
Inhalation of exhaust gases can result in serious personal injury or death. DO NOT use
the air cleaner or exhaust elbow as a supporting step. Damage of these and connecting
parts might cause an exhaust leak.
WARNING
WARNING
Accidental Starts!
Before servicing the engine or equipment on the machine, always disconnect the spark plug leads to
prevent the engine from starting accidentally. Ground the leads to prevent sparks that could cause
fires.
These required maintenance procedures should be performed at the recommended intervals. They
should also be included as part of any seasonal tune-up. Refer to Table 6-1 for regularly scheduled
maintenance. The following guidelines should also be followed:
• Check fluid level in battery regularly.

independently of engine operation. Under normal operation, no service of this clutch is required. If
the V-grooves should become worn, a completely new clutch assembly (Crafco part number 31289)
must be installed (Figure 6.8).
6.11 Dust Control Router Specific Maintenance
The following maintenance instructions are for parts used on dust control equipped Model 30
Pavement Routers.
Dust Collection Bag Maintenance 6.11.1
The dust collection bag should be cleaned on a daily basis or more frequently depending on asphalt
conditions to ensure maximum dust collector efficiency. To clean the dust collection bag, remove
the dust collection bag from the router. Open the zipper on the dust collection bag to access the
inside of the dust collection bag.
try to forcibly open the zipper or damage to the dust collection bag may occur. Gently work the
slider of the zipper back and forth to work the dust out of the elements until the zipper is completely
Use a Shop Vac to vacuum the entire inside of the dust collection bag. If shop air is to be used to

Table 6-8 Changing Seal Brushes
Maintenance Instructions
Do Not try to clean the dust collection bag with water. Keep the dust collection bag dry at all times,
whether when in use or during transport and storage. Water, rain or significant moisture may cause
the bag to shrink and not function appropriately.
Cutter Head Dust Shroud 6.11.2
When seal brushes become worn and stop trapping dust behind the shroud, they should be
replaced. If brushes become deformed they can be soaked in hot water for approximately 20 min.
This will aid in the brushes regaining their shape. Allow brushes to dry before using. If the shroud is
showing wear or damage beyond the extent of brush wear, the entire shroud should be replaced.

The Model 30 Pavement Router uses 12-volt dir ect current (DC) to power the engine, and actuator
motor. The DC power is from a 12-volt battery.
12-volt DC power has little danger of electrical shock. Care must still be taken when dealing with
DC power systems because it is capable of producing large amounts of current.
7.1 Checking DC Voltage with a Multimeter
Connect the probes to the meter.
Set the range to a position that includes 12-volts or higher.
Touch the red probe to the positive side of accessory and black probe to ground. If the item you
are checking has a ground wire attached then use that ground or you can use the grounding stud
on the engine channel assembly.
7.2 Checking Resistance (Ohms)
Connect probes to the meter (See Figure 7.1 Standard Multimeter).
Note: When checking Ohms the circuit cannot be completed. This means one end of the wire will
need to be disconnected.
7.3 Checking Wire Continuity
Set the meter to “Audible Continuity”.
Now touch the probe to each end of the wire in question. The meter will read “0” on the screen and
make an audible beep if the wire has continuity from end to end.

The following sections illustrate the spacing options for the different types of cutter heads available.
Cutter Positioning for Cutter Part Numbers 31134, 31136, 31137, 31149 9.11.1
Cutters can be aligned or staggered to configure the desired cut width. For wider cutting additional cutter
can be added to a single pin to achieve a smoother finished cut. Always use enough Hardened Spacers to
keep cutters appropriately positioned on the pin while still allowing the cutter to turn completely free.
Cutter Position for Cutter Part Number 31135 Shaved Cutter 9.11.2
Cutters can be aligned to configure the desired cut width. For wider cutting additional cutters can be added
to a single pin to achieve a smoother finished cut. Always use enough Hardened Spacers to keep cutters
appropriately positioned on the pin while still allowing the cutter to turn completely free. The main
consideration is placing equal number of cutters and spacers on opposite pins to maintain balance. Failure
to do so could result in permanent damage to the machine and possibly injury to the operator.
