Torque Specifications
Recommended fastener torque values are listed in the following tables. For critical applications, as determined by Toro, either the recommended torque or a torque that is unique to the application is clearly identified and spe­cified in this Service Manual.
These Torque Specifications for the installation and tightening of fasteners s hall apply to all fasteners which do not have a specific requirement identified in this Ser­vice Manual. The following factors shall be considered when applying torque: cleanliness of the fastener, use of a thread sealant (e.g. Loctite), degree of lubrication on the fastener, presence of a prevailing torque feature, hardness of the surface underneath the fastener’s head or similar condition which affects the installation.
Fastener Identification
As noted in the following tables, torque values should be reduced by 25% for lubricated fasteners to achieve the similar stress as a dry fastener. Torque values may also have to be reduced when the fastener is threaded into aluminum or brass. The specific torque value should be determined based on the aluminum or brass material strength, fastener size, length of thread en­gagement, etc.
The standard method of verifying torque shall be per­formed by marking a line on the fastener (head or nut) and mating part, then back off fastener 1/4 of a turn. Measure the torque required to tighten the fastener until the lines match up.

FITTING
ProForce blowers with serial number above 310000000 are equipped with a fuel evaporative control system (EVAP) designed to collect and store evaporative emis­sions from the fuel tank. The EVAPuses a carbon canis­ter to collect these evaporative emissions. Fuel vapors from the fuel tank are vented to the canister where they are stored. Vapors from the canister are consumed when the engine is running which purges the canister.
The fuel tank o n these ProForce machines uses a non-­vented fuel cap. To connect the tank to the evaporative control system, a fuel vent valve is positioned in the top of the tank that allows tank venting through the carbon canister.
NOTE: If there is restriction in the fresh air filter, the car­bon canister or the fuel vent valve, the fuel tank may dis­tort due to venting issues. I f the fuel tank returns to it’s normal shape when the fuel cap is removed, restriction in the evaporative control system is likely.
Machines with a carbon canister include a single engine connection to the engine intake system that is used to connect the evaporative system to the engine. These machines use an inline check valve and fuel filter between the carbon canister and the engine fitting. Evaporative control system components for ProForce blowers are shown in Figure 11.

Electrical System Quick Checks
Battery Test (Open Circuit Test)
Use a digital multimeter to measure the battery voltage.
Set the multimeter to the DC volts setting. The battery should be at a temperature of 60 C). The ignition switch should be in the OFFposition and all accessories turned off. Connect the positive (+) multi­meter lead to the positive battery post and the negative (--) multimeter lead to the negative battery post. Record the battery voltage.
NOTE: This testprovides a relative condition of the bat­tery. Load testing of the battery will provide additional and more accurate information (see Battery Service in the Service and Repairs section).
o
to 100oF(16oto 38
Charging System Test
This is a simple test used to determine if a charging sys­tem is functioning. It will tell you if the charging system has an output, but not its capacity.
Use a digital multimeter set to DC volts. Connect the positive (+) multimeter lead to the positive battery post and the negative (--) multimeter lead to the negative bat­tery post. Keep the test leads connected to the battery posts and record the battery voltage.
Voltage Measured
12.68 volts Fully charged (100%)
o
Start the engine and run at high idle (3450 RPM). Allow the battery to charge for at least 3 minutes. Record the battery voltage.
After running the engine for at least 3 minutes, battery voltage shouldbe at least 0.50 volthigher than initial bat­tery voltage.
An example of a charging system that is functioning:
12.45 volts 75% charged
12.24 volts 50% charged
12.06 volts 25% charged
11.89 volts 0% charged
Battery Charge Level
NOTE: Upon starting the engine, the battery voltage
will drop and then should increase once the engine is running.
NOTE: Depending upon the condition of the battery charge and battery temperature, the battery voltage will increase at different rates as the battery charges.
At least 0.50 volt over initial battery voltage.
Initial Battery Voltage = 12.30 v
Battery Voltage after 3 Minute Charge = 12.85 v
Difference = +0.55 v

Relays
The electrical system on all P roForce Debris Blowers in­cludes a fuel relay that is used t o energize the engine carburetor fuel solenoid. When the ignition switch is in the RUN or START position, the fuel relay is energized by the Wireless Control Module.
ProForce blowers with serial numbers below 310000000 include a second relay. The power relay on these machines is used to provide machine electrical power when it is energized by the Remote Control Mod­ule.
ProForce blower models 44538 and 44539 with serial numbers above 312000000 include an additional three (3) relays: a start relay and two (2) relays for energizing the chute rotation motor. These relays are energized by the Wireless Control Module when a remote transmitter input is entered for engine starting or chute rotation.
The relays are secured to the control tower bracket next to the engine. The relays can be identified by the wire colors at the wire harness connector (see Wire Harness Drawings in Chapter 7 -- Electrical Diagrams).
Test i n g
4. Using a multimeter (ohms setting), measure coil re­sistance between terminals 85 and 86 (Fig. 14). Resist­ance should be between 70 and 90 ohms.
5. Connect multimeter (ohms setting) leads to relay ter­minals 30 and 87. Ground terminal 86 and apply +12 VDC to terminal 85. The relay should have continuity be­tween terminals 30 and 87 as + 12 VDC is applied to ter­minal 85. The relay should not have continuity between terminals 30 and 87 as +12 VDC is removed from termi­nal 85.
6. Disconnect voltage and multimeter leads from the relay terminals.
7. Connect multimeter (ohms setting) leads to relay ter­minals 30 and 87A. Ground terminal 86 and apply +12 VDC to terminal 85. The relay should not have continuity between terminals 30 and 87A as +12 VDC is applied to terminal 85. The relay should have continuity between terminals 30 and 87A as +12 VDC is removed from ter­minal 85.
8. Disconnect voltage and multimeter leads from the relay terminals.
1. Make sure that ignition switch is OFF.
2. To prevent unexpected machine operation, discon­nect the negative battery cable from the battery terminal (see Battery Service in the Service and Repairs section of this chapter). Position disconnected negative cable away from the negative battery terminal.
3. Locate relay and disconnect the machine wire har­ness connector from the relay. Remove relay from ma­chine for easier testing.
NOTE: Prior to taking small resistance readings with a digital multimeter, short the meter test leads together. The meter will display a small resistance value (usually
0.5 ohms or less). This resistance is due to the internal resistance of the meter and test leads. Subtract this val­ue from the measured value of the component you are testing.
9. Secure relay to machine and connect machine wire harness connector to relay.
10.Connect negative battery cable to n egative b attery terminal. Tighten nut that secures battery cable from 10 to 15 ft--lb (14 to 20 N--m). Make sure that battery cover is secured.

Remote Transmitter (Machines with Single Channel Controller)
NOTE: Machines with a single channel controller can
be identified by the external antenna on the control mod­ule (Fig. 15).
The remote transmitter is a solid state electrical device that sends radio frequency (RF) signal inputs to the ma­chine control module for control of machine electrical operation (Fig. 15). The remote transmitter has suffi­cient range to send an RF signal to the control module from the tow vehicle operator position.
Whenabuttonontheremotetransmitter is pressed, the LED on the remote should flicker (Fig. 16). If the ma­chine control module is energized (control module Time Out andPower LED’s are both illuminated) and a remote transmitter button is pressed, the corresponding control module LED should illuminate and the control module RF activity LED should flicker.
If the control module is energized (control module Time Out and Power LED’s are both illuminated), remote but­ton functions are as follows:
Pressing the Engine Start button initiates a starting se­quence to start the engine. This sequence (see Opera­tor’s Manual) is necessary to prevent accidental engine starting. After pressing the Engine Start button, the RH Nozzle and LH Nozzle Rotate buttons are inactive for five (5) seconds.
Pressing the Speed Increase (rabbit) button when the engine is running causes the engine speed to increase.
Remote Transmitter Battery Replacement
1. Remove six (6) screws t hat secure the rear cover to the remote transmitter.

Remote Transmitter (Machines with Multi Channel Controller)
NOTE: Machines with a multi channel controller can be
identified by the lack of an external antenna on the con­trol module (Fig. 17).
NOTE: Additional information regarding the remote transmitter is included in the Operator’s Manual.
The remote transmitter is a solid state electrical device that sends radio frequency (RF) signal inputs to the ma­chine control module for control of machine electrical operation (Fig. 17). The remote transmitter has suffi­cient range to send an RF signal to the control module from the tow vehicle operator position.
When a button on the remote transmitter is pressed, the TX LED on the remote should illuminate and then blink (Fig. 18). If the machine control module is energized (control module health LED is illuminated) and a remote transmitter button is pressed, the control module TX/RX LED should blink.
If the control module is energized(control module health LED is illuminated), remote transmitter button functions are as follows:
Pressing the Engine Start button initiates a starting se­quence to start the engine. This sequence (see Opera­tor’s Manual) is necessary to prevent accidental engine starting. If any transmitter buttons are pressed out of or­der during the starting sequence, the sequence will be aborted.
The remote transmitter is powered by three (3) AAA al­kaline batteries. If the range of the transmitter has dimin­ished or the transmitter TX LED does not illuminate when a button is pressed, the transmitter batteries should be replaced.

Wireless Control Module (Machines with Single Channel Controller)
NOTE: Machines with a single channel controller can
be identified by the external antenna on the control mod­ule (Fig. 15).
The wireless control module is a solid state electrical de­vice that receives signal inputs from the remote trans­mitter and uses those inputs to control machine electrical operation. The control module is attached to the frame next to the battery (Fig. 19).
Inputs from the ignition switch and the remote transmit­ter are monitored by the control module. Output to the magneto relay, fuel relay, power relay, engine starter motor solenoid, engine throttle control module and nozzle rotation motor are controlled based on the inputs received by the control module.
To start b lower operation, rotation of the ignition switch to the START position is used to turn on or “wake up” the control module. The control module Time Out and Pow­er LED’s should both be illuminated during blower op­eration (Fig. 20).
When a remote transmitter button is pressed, the corre­sponding control module LED should illuminate and the control m odule RF activity LED should flicker (Fig. 20).
NOTE: Because of the normal RF activity in the envi­ronment, the control module RF activity LED may flicker or be illuminated at any time during machine operation. Machine operation will only be controlled by the remote transmitter that is recognized by the control module.
NOTE: Whentheenginestopbuttonontheremote transmitter is pressed, there will be a one (1) second delay before the control module engine stop LED illumi­nates. Also, the control module engine stop LED will re­main illuminated and no other remote transmitter operations can be performed for about five (5) seconds.
The control module includes a time--out feature to allow machine operation for a time period after the last control input (e.g. key switch turned off or remote transmitter button pressed). If no inputs are provided to the control module during this time period, the control module will shut off all machine electrical power including turning off the engine, if running. When the engine is turned off with either the key switch or the remote transmitter, the con­trol module Time Out and Power LED’s will both be illu­minated for this time period. Refer to your Operator’s Manual for additional details on the time--out feature.
The control module does not connect to an external computer or hand held device, can not be re--pro­grammed and does not record any fault data. The ma­chine wire harness does include a communication port with loopback connector that should remain connected.
Because of the solid state circuitry built into the control module, thereis no reliablemethod to testit. The module maybedamagedifanattemptismadetotestitwithan electrical test device, such as a digital multimeter.
IMPORTANT: Before performing any welding on the machine, disconnect the negative battery cable from the battery and the wire harness connector from the wireless control module to prevent dam­age to the electrical system.

Wireless Control Module (Machines with Multi Channel Controller)
NOTE: Machines with a multi channel controller can be
identified by the lack of an external antenna on the con­trol module (Fig. 21).
The wireless control module is a solid state electrical de­vice that receives signal inputs from the remote trans­mitter and uses those inputs to control machine electrical operation. The control module is attached to the frame next to the engine.
Inputs from the machine ignition switch and the remote transmitter are monitored by the control module. Output to the fuel relay, start relay, engine starter motor sole­noid, engine throttle control module and nozzle rotation relays are controlled based on the inputs received by the control module.
To start blower operation, rotation of the ignition switch totheSTARTpositionisusedtoturnonor“wakeup”the control module. The control module Health LED should be illuminated green during normal blower operation (Fig. 22). If the Health LED is illuminated either yellow or red, a problem exists with the controller.
When a remote transmitter button is pressed, the control module TX/RX LED should flicker (Fig. 22). The TX/RX LED will be green when the module is receiving a signal from the remote and will be red when the module is transmitting.
IMPORTANT: Before performing any welding on the machine, disconnect the negative battery cable from the battery and the wire harness connector from the wireless control module to prevent dam­age to the electrical system.

Electrical
System
NOTE: Because of the normal RF activity in the envi-
ronment, the control module TX/RX LED may flicker or be illuminated at any time during machine operation. Machine operation will only be controlled by the remote transmitter that is associated to the control module.
The control module includes a power save mode if the module is active for more than 2.5 hours without com­munication from the remote transmitter. Once in the power save mode, the control module will not commu­nicate with the remote transmitter, will not activate any machine outputs and will not function normally. All ma­chine electrical power will be shut--off including turning off the engine, if running. Refer to your Operator’s Manual for additional details on the power save mode.
The control module does not connect to an external computer or hand held device, can not be re--pro­grammed and does not record any fault data. Because of the solid state circuitry built into the control module, there is no reliable method to test it. The module may be damaged if an attempt is made to test it with an electrical test device, such as a digital multimeter.

Battery Storage
If the machine will be stored for more than 30 days:
1. Remove the battery from the machine and charge it fully (see Battery Service).
2. Either store battery on a shelf or on the machine.
3. Leave battery cables disconnected if the battery is stored on the machine.
Battery Care
1. Battery electrolyte level must be properly main­tained. The top of the battery must be kept clean. lf the machine is stored in a location where temperatures are extremely high, the battery will discharge more rapidly than if the machine is stored in a location where temper­atures are cool.
CAUTION
Wear safety goggles and rubber gloves when working with electrolyte. Charge battery in a well ventilated place so gasses produced while charging can dissipate. Since the gases are ex­plosive, keep open flames and electrical sparks away from the battery; do not smoke. Nausea may result if the gases are inhaled. Unplug char­ger from electrical outlet before connecting or disconnecting charger leads to or from battery posts.
IMPORTANT: Do not remove battery fill caps while cleaning.
2. Check battery condition weekly or after every 50 hours of operation. Keep terminals and entire battery case clean because a dirty battery will discharge slowly.
4. Store battery in a cool atmosphere to avoid quick de­terioration of the battery charge.
5. To help prevent the battery from freezing, make sure it is fully charged (see Battery Service).
3. Battery cables must be tight on terminals to provide good electrical contact. Tighten nuts that secure battery cables from 10 to 15 ft--lb (14 to 20 N--m).
CAUTION
Connecting battery cables to the wrong bat­tery post could result in personal injury a nd/or damage to the electrical system.
4. If corrosion occurs at battery terminals, disconnect cables. Always disconnect negative (--) cable first. Clean clamps and terminals separately. Reconnect cables to battery with positive (+) cable first. Coat bat­tery posts and cable connectors with Battery Terminal Protector (Toro Part No. 107--0392) or petroleum jelly to prevent corrosion.
5. Periodically (at least every 50 operating hours) check battery electrolyte level. Check electrolyte level every 30 days if m achine is in storage.
6. Maintain battery cell level with distilled water. Do not fill battery cells above the fill line.
A. Clean battery by washing entire case with a solu­tion of baking soda and water. Rinse with clear water.
B. Coat battery posts and cable connectors with Battery Terminal Protector (Toro Part No. 107--0392) or petroleum jelly to prevent corrosion.

Battery Inspection and Maintenance
1. Check battery case for cracks. Replace battery if cracked or leaking.
2. Check battery terminals for corrosion. If corrosion occurs at terminals, disconnect cables. Always discon­nect negative (--) cable first. Clean cable clamps and battery terminals separately. Reconnect cables with positive (+) cable first. Coat battery posts and cable con­nectors with Battery Terminal Protector (Toro Part No. 107--0392) or petroleum jelly to prevent corrosion.
IMPORTANT: Before cleaning the battery, tape or block vent holes to the filler caps and make sure the caps are on tightly.
3. Check for signs of wetness or leakage on the top of the battery which might indicate a loose or missing filler cap, overcharging, loose terminal post or overfilling. Also, check battery case for dirt and oil. Clean the bat­tery with a solution of baking soda and water, then rinse it with clean water.
4. Check that the cover seal is not broken away. Re­place the battery if the seal is broken or leaking.
5. Check the electrolyte level in each cell. If the level is below the tops of the plates in any cell, fill all cells with distilled water between the minimum and maximum fill lines. Charge at 15 to 25 amps for 15 minutes to allow sufficient mixing of the e lectrolyte.

C. If the difference between the highest and lowest cell specific gravity is 0.050 or greater or the lowest cell specific gravity is lessthan 1.225, chargethe bat­tery. Charge at the recommended rate and time giv­en in Charging or until specific gravity of all cells is
1.225 or greater with the difference in specific gravity between the highest and lowest cell less than 0.050. If these charging conditions can not be met, replace the battery.
2. Perform a high--discharge test with an adjustable load tester.
This isone of themost reliable means of testing a battery as it simulates the cold--cranking test. A commercialbat­tery load tester is required to perform this test.
C. Make sure battery terminals are free of corrosion.
D. Measure the temperature of the center battery cell.
E. Connect a battery load tester to the battery termi­nals following the load tester manufacturer’s in- structions. Connect a digital multimeter to the battery terminals.
F. Apply a testload of 270 amps (one half the Crank­ing Performance rating of the battery) for 15 se­conds.
G. Take a voltage reading after 15 seconds, then re­move the load.
H. Using the table below, determine the minimum voltage for the cell temperature reading:

CAUTION
Do not charge a frozen battery because it can ex­plode and cause injury. Let the battery warm to
o
F (15.5oC) before connecting to a charger.
60
Charge the battery in a well--ventilated place to dissipate gases produced from charging. These gases are explosive; keep open flame and elec­trical spark away from the battery. Do not smoke. Nausea may result if the gases are inhaled. Un­plug the charger from the electrical outlet before connecting or disconnecting the charger leads from the battery posts.
3. Following the battery charger manufacturer’s instructions, connect the charger cables to the battery.
Make sure a good connection is made.
4. Charge the battery following the battery charger manufacturer’s instructions.
5. Occasionally check t he temperature of the battery electrolyte. If the temperature exceeds 125 or the electrolyte is violently gassing or spewing, the charging rate must be lowered or temporarily stopped.
6. Three hours prior to the end of the charging, mea­sure the specific gravity of a battery cell once per hour. The battery is fully charged when the cells are gassing freely at a low charging rate and there is less than a
0.003 change in specific gravity for three consecutive readings.

NOTE: The rotor shaft and bearings can be serviced
without removing inner housing (item 23) from machine (see Rotor Shaft in this section). For replacement of the inner housing, stator vanes (item 10) or outer housing (item 12), the following procedure is necessary.
NOTE: ProForce Blowers have used three (3) methods of securing the inner and outer housings. On machines with serial number below 310000000 (Fig. 13), the inner housing is attached directly to the outer housing. Onma­chines with serial number from 310000000 to 313000000, a fin spacer and possibly additional thin spacers exist between the inner housing flanges and the outer housing (Fig. 14). Machines with serial number above 313000000 use four (4) fin mounts with fin spacers and possibly additional thin spacers that are se­cured between inner housing and outer housing (Fig.
15). Refer to correct illustration when removing and in­stalling inner and outer housings.
