Start with the brushes - they are either worn low or the brush tubes are causing them to stick so they don't contact the armature - this is why it starts when you 'rap' it.
Running slow can be a bad armature or field from running hot because of the bad brush connection.
1) remove the brushes
2) remove the 4 bolts holding the motor to the saw
3) pull the armature out and inspect for signs of being burnt (especially look at the copper commutators where the brushes sit)
4) inspect the field for signs of being burnt

2002 buick lesabre limited Radio stays on even with key off and door open


Could have a problem with (RAP) Retained Accessory Power.
Relay Control of Retained Accessory Power (RAP)
Retained accessory power (RAP) is a vehicle power mode that permits the operation of selected customer convenience items after the ignition switch is turned OFF. These selected items will remain in operation until a passenger compartment door is opened or until the RAP function timer reaches its shut-off limit.
When the RIM module is in the RAP function as described above, it closes the RAP relay. This provides power during the RAP period for the components supplied by the RAP relay.
The RIM module opens the RAP relay to end the RAP function when it ends the RAP function as outlined in the previous text.
© 2017 General Motors Corporation. All rights reserved.

The modules listed below all receive a RAP message from the dash integration module (DIM) module over the serial data circuits. The DIM module monitors the ignition switch position, battery condition and passenger compartment door status to determine whether RAP should be initiated. The DIM module then sends a message to the listed modules telling them that they are in RAP power mode. The modules then support the operation of the systems under their control as required by their RAP power mode strategy.
RAP will end when one of the following conditions are met:
• The DIM module receives an input as a serial data message from the driver door module (DDM) indicating the opening of a passenger compartment door.
• The DIM module receives a message from its internal timer indicating the end of the RAP period after 10 minutes.
• The DIM module detects a decrease in battery capacity below a prescribed limit.
• The transition from OFF to RUN/ON or ACC of the ignition switch.



The DIM module then sends a serial data message to the listed modules ending the RAP function.
The modules receiving serial data messages for RAP functions are:
• The driver door module (DDM)
• The radio
• The rear integration module (RIM)
• The vehicle communication interface module (VCIM)-Generation F1
• The vehicle interface unit (VIU)-Generation 2.6

The Rap relay could be bad (stuck contact's ) or one of the three module's that make up the body control system . Having the vehicle checked for DTC'S - diagnostic trouble codes should be the first step in diagnosing this type problem .

06 Pontiac torrent radio continues to run when ignition is in off and key removed, even after drivers door opened, passenger door open then radio stops


Driver door switch ,ajar switch . This switch is a input to the BCM - body control module .
Retained Accessory Power Description and Operation
Retained accessory power (RAP) is a vehicle power mode that permits the operation of selected customer convenience items after the ignition switch is turned OFF. These selected items will remain in operation until a passenger compartment door or liftgate is opened or until the RAP function timer reaches its shut-off limit.
The class 2 RAP power mode is mapped to GMLAN serial data circuit as Off Awake power mode. Refer to Data Link Communications Description and Operation for more information on data link communications. The BCM monitors the ignition switch signals, battery condition and the doors status to determine whether RAP should be initiated. The modules that support the RAP power mode will operate the systems under their control as required by their RAP power mode strategy.
RAP will end when one of the following conditions is met:
• The BCM detects the opening of a passenger compartment door.
• The RAP timer expires.
• The battery capacity decreases below a prescribed limit.
• Any other ignition switch state is chosen.
The function supported in the RAP power mode is the operation of the radio.

It would go off on it's own in ten min.

My dewalt dw712 cuts out of square. How do I fix it ?


I've been in construction for 49 years. I never use the guide or laser because there are some blades that are thicker than others, especially the blade that comes from the factory. It is one of the thinnest. I always guide the side of the blade with the line while I am cutting.

2003 Range rover won't start


Very likely the fuel pump has failed, if you mean you tapped on the gas tank
and it finally started. When a pump fails, sometimes rapping on the tank will re-energize it briefly or maybe even a couple of times before it gives out for good.
If you were tapping on the gas pedal, though, and it just started, your mechanic will have to look at it. Too many electrical fault possibilities, Scott, it needs proper diagnosis to find the p[roblem.

My mitsubishi tv W55613 won't turn on. green light keeps blinking even after resetting


Hit the front of the tv near the blinking light... give it a good rap or two. See if this helps. Helped mine. I had the same problem and the tech who came out to the house told me that it would work and it did! I could hardly believe it but it worked.

I have a series 51 husky saw. it starts and runs normally until it gets up to operating temps. then it stalls out and either refuses to restart or just won't restart until it cools down again....


sounds like air fuel mixture screws are out of adjustment..start with the on marked (L)..this is the low speed(idle) adjustment...turn it in all the way just until it stops..but be gentle..then you wnat to turn it out 1 1/2 turns as a starting point..start the engine and adjust it until you get a smooth idle...next, with the saw running, pull the trigger and you should have a smooth response from slow to fast...you can adjust the (H) screw until you get good high speed operation...if these adjustments don't fix the problem thenm yoou may need to have the carb rebuilt( a carb kit is usually only 15-30 dollars)

Stater won`t stop


The starter circuit is completing somewhere. Have a look at your start button and/or solenoid. It could be mucky contacts, if so give them a clean.
