Accidental engine starting can cause injury or death to personnel working on the equipment. To avoid accidental engine starting, disconnect the battery cable from the negative (−) battery terminal. Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact with other metal surfaces which could activate the engine electrical system. Place a Do Not Operate tag at the Start/Stop switch location to inform personnel that the equipment is being worked on. |

Personal injury or death can result from improper lifting or blocking. When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component. Approximate weights of the components are shown. Clean all surfaces where parts are to be installed. |

Installing the "myBHL" App (iOS)
- Using an iPhone, enter the Apple App Store.
- Enter the term "myBHL" in the search box and hit "Enter".
- Select the Cat® myBHL app and install the app on the phone.
Preparing to Connect for the First Time
- On the iPhone, enter the "Settings" menu.
- In the settings menu select "Bluetooth".
Note: Within the Bluetooth menu turn ON Bluetooth if necessary.
- Turn the ignition key of the machine to the RUN position.
Note: The engine does not have to be running in order to connect the Bluetooth device.
- In the Bluetooth menu on the iPhone, in the devices list, look for "CAT myBHL". The device listed will have the naming format "CAT myBHL-XXXX".
- Select the "CAT myBHL" Bluetooth module and enter the Bluetooth pairing PIN code when prompted.
Note: The "CAT myBHL" Bluetooth module will be powered for 30 seconds after turning the ignition key to the RUN position. After this time, the machine will stop searching for Apple devices to connect to and enter standby mode. If a connection is not made during this 30 second period, a cycle of the ignition key to OFF and back to RUN is needed to turn the module back on, and restart the timer.
- Open the "myBHL" App. This action will automatically connect the phone to the machine.
- Once the connection is confirmed, exit the "myBHL" app and turn the ignition key of the machine to the OFF position.
From now on, the machine will connect to the CAT myBHL app automatically.
Note: Once the initial pairing process has been completed, the sequence of turning on the machine or entering the app is irrelevant. However, if the app is entered for more than 30 seconds after starting the machine, pairing may take up to one minute for the app to connect.
