Components Wheel Balancer components include: • Display Panel. Shows balance and test mode data when using the Balancer. • Cover. Protects the operator from the Wheel while it is in motion. • Inner Arm / Distance Ruler. Used to determine the Distance between the Balancer and the inner edge of the Wheel being balanced.
Page 7
Balancer accessories include: • Quick-Release Hub Nut. Holds the Wheel on the Balancer once the Wheel is mounted. • Hex Key Wrenches. Used during installation. Hex key wrenches are sometimes called Allen® wrenches. • Anchor Bolts. Anchor the Balancer to the floor at the desired location. Anchoring the Balancer is optional, but strongly recommended.
• Dynamic Balancing. Balancing a steel Wheel where each of the two planes are analyzed separately. If there is an imbalance, the two planes are brought back into balance separately. Dynamic Balancing is newer technology than Static Balancing and generally provides a better balance.
Installation Checklist Following are the steps required to install the LS45DS Wheel Balancer. Perform them in the order shown. ☐ 1. Review the installation Safety Rules. ☐ 2. Plan for Electrical Work. ☐ 3. Make sure you have the necessary Tools. ☐...
Certain parts of installing the Balancer are difficult for just one person. BendPak CAUTION Ranger strongly recommends having two or more persons working together to install the Balancer. If you have to use an extension cord, make sure its current rating is equal to or greater than that of the equipment being used.
Find a Location Keep in mind the following when deciding on a location: • Power source. The Balancer needs to be near an appropriate 220 VAC power source. • Floor. The Balancer is best used on a flat, concrete floor. If the floor is unstable or not flat, the Balancer will not function correctly and will create faulty balance results.

Installing the Display Panel The Display Panel shows information about what is happening during the balancing of a Wheel. To install the Display Panel: 7. Locate the Display Panel and the Display Panel Support. – The Display Panel Base Plate (located on the bottom of the Display Panel Support, connects to the back of the Balancer using four hex bolts, four split lock washers, and four standard washers;...
Page 17
Connections on the Back of the Balancer Make the electrical connections on the back panel. • Display Cable and Connector. Connects to the back of the Balancer via the Display Panel Base Plate Five-Pin Connector refer to the figure below. •...
Installing the Shaft The Shaft supports the Wheels you are balancing. Consider having two assistants to install the Shaft: one to hold the Shaft Assembly in place while the second person screws in the Mounting Bolt. Also, consider having shop towels nearby as the Shaft is shipped with a heavy protective grease coating.
M10 diameter Anchor Bolt, for example, use an M10 diameter drill bit. 3. Clean each hole. Ranger recommends using a vacuum to clean the hole. Do not ream the hole. Do not make the hole any wider than the drill bit made it.
Even using a hammer or mallet, the Anchor Bolt should only go into the hole part of the way; this is normal. If the Anchor Bolt goes all the way in with little or no resistance, the hole is too wide. Once past the hole in the Base Plate, the Anchor Bolt eventually stops going down into the hole as the Expansion Sleeve contacts the sides of the hole;...
• The Balancer includes a case (chassis) ground terminal. In case of installations in a high EMF environment with strong induced currents that could interfere with the balance measurements connect this terminal to ground. • Damage caused by improper electrical installation voids the warranty. •...

Viewing Information on the Display Panel Data about the Wheel you are balancing, and the test modes is provided on the Display Panel. There are no controls or buttons on the Display Panel, only information. Note: The Display Panel is separated into sections: •...
Page 24
• Indicators around the Wheel. When Weight correction needs to be added to a Wheel, raise the Cover, and turn the Wheel slowly by hand while watching the indicators on the appropriate side of the Wheel. When all of the indicators are lit, the Wheel will lock automatically, and the laser will indicate the exact spot to place the Weight.
About Planes If you were to split a Wheel down the center (as shown below), it would be divided into two “Planes,” an Inner plane and an Outer plane. Balancing a Wheel on both planes at the same time is the most effective method. Of the five Balancing Modes (DYN, STA, ALU1, ALU2, and ALUS) supported by the LS45DS, four of them balance on both planes at the same time.
Page 26
Because balancing a Wheel on both planes is critical to using the LS45DS, the Display Panel shows a two-plane view of the Wheel being balanced. The Inner “Plane” is on the left (based on the main placement method for Wheels on the Balancer, where the visible Rim on the outside) and the Outer “Plane”...
About Measurements There are three Wheel measurements that are important to understand for correct balancing. The LS45DS determines these measurements automatically when you use the Inner Arm and the Sonar. The three measurements are: • Distance. The distance from the side of the Balancer to the Inner Edge of the Wheel. Measured by the Inner Arm.
Page 28
The LS45DS Control Panel The Control Panel is used to input data and control aspects of the Balancer during both the Measurements and Weights phases. • Distance, Width, Diameter + / — buttons. Used to change the Distance, Width, and Diameter settings during the Measurements phase of the balancing session (before the Wheel is spun).
Page 29
Mounting a Wheel When you want to balance a Wheel, the first step is to mount it on the Shaft. Important: All Wheels should be mounted so that the inside goes on the Shaft first. There are three methods to mount a Wheel onto the Shaft using the Collets supplied with the Balancer: •...
Page 30
• Dual-Collet Mounting. Generally used only for some aftermarket or OEM performance Wheels that have a center hole that is deep enough to allow the use of two Collets on the Shaft. The Spring goes on first, then an appropriately sized Collet, the Wheel, a second appropriately sized Collet, and finally the Quick Nut.

2. The Lug-Centric Plate is delivered with three sets of Lug Pins (5 each) to address wheels that use Tapered and Radius (Ball) Tapered Lug Bolts. a. 92mm Lug Pin for Tapered Lug Bolts (use with wide wheels) b. 114mm Lug Pin for Tapered Lug Bolts (use with narrow wheels) c.
Balancing Modes Balancing Modes (5 Modes) are based on the locations where the weight is installed to balance the Wheel: • Dynamic (DYN). The most common Balancing Mode; used with steel rims, and when weights placed on the visible side of the wheel is not a concern to the customer. If the Wheel is out of balance, weights go on the Inner Edge and the Outer Edge.
OPT (Optimize) Function Not a Balancing Mode. The Optimize Function is an optional procedure to lessen the imbalance in a Wheel that is more than 3 ounces (90 grams) out of balance. For more information, refer to Using the Optimize Function.
Dynamic Balancing Dynamic Balancing evaluates and balances a Wheel with weights clipped to both the Inner and Outer Edges. The Clip-On Weight may be installed on the Inner Edge, the Outer Edge, or both. To Balance a Wheel using Dynamic Mode: 1.
Page 35
7. Lower the Cover to automatically determine the width and to evaluate the wheel for balance. This data may also be entered manually. If you wish to turn off the automatic spin feature, press and hold STOP, then press C. You will then be required to press START to spin the Wheel. To turn the Automatic Spin feature back on, repeat the same process.
Page 36
14. Press Stop to release the Wheel from the automatic lock. 15. Turn the Wheel slowly again to find the best location for weight on the Outer Edge (again, assuming it needs weight; if the Outer Window shows 00, do not add weight to the Outer Edge). 16.

Upper and Lower Laser Instructions ⚠ WARNING Do not look directly into the laser. Doing so may damage your eyes. Upper Laser Instructions. The Laser will clearly define the inside and outside Weight position in Dynamic Balancing Mode. 1. The Laser function is enabled when the Dynamic Balancing Mode is selected.
Static Balancing Static Balancing is typically for older Wheels, vintage custom wheels, and similar. Typically, where the customer does not want weights either visible and/or applied to a chrome or polished surface. Also used when rims measure under 4 inches wide and with most motorcycle Wheels. Note: The Optimize Function is not available for Static Mode.
Aluminum Alloy Balancing The following procedure describes the three Aluminum Alloy (ALU) Modes available. Important: ALU Modes are for balancing Wheels made of aluminum alloy. The weights can be placed in various locations on these Wheels. Determine where the weights are to be applied, and then select the appropriate ALU Mode.
Page 40
g. The Balancer displays the correction weights for the inner and outer planes shown on the display panel. h. Spin the wheel by hand slowly until all the indicators are illuminated on either the Outer or Inner Planes. The balancer will automatically lock the wheel position and a laser generated line will indicate the weight location on the Wheel.
Page 41
h. Place the correction Weight on the Wheel at the 6 o’clock position for the Center Plane and 12 o’clock position for the Inner Edge as indicated by the laser. Press STOP to unlock the Wheel. Spin the wheel slowly by hand again until the opposite plane indicators are all lit, and the balancer locks the tire.
Page 42
ALUS without the Lower Laser ALUS Mode without the Laser uses the Inner Measurement Arm to apply the correction weights on the Inner and Center Plane. a. Verify the Lower Laser is in the Off condition. b. Pull out the Inner Arm, place it on the Inner Plane, and hold it there. See figure below. c.
n. Place the correction weight on the Inner Arm Gauge Head and pull the inner Arm out until the Center Window displays – – . o. Lift up the Lift Arm Gauge Head and apply the Weight. p. Return the Inner Arm Gauge to its rest position.
Page 44
Do not return the Inner Arm to its rest location between the two locations. See figure to the right. 9. Listen for the beep. 10. After the beep, return the Inner Arm to the rest position. 11. Make sure that the ALUS mode indicator is lit on the Display Panel (the Balancer should enter this mode automatically when the Inner Arm is returned to its rest position).
Page 45
19. The Inner and Outer Display Windows should now display -2-. 20. Rotate the wheel to bring the next closest Wheel Spoke to the left of the ideal weight location to the 6 o’clock position. Press ALU. See the figure below. This indicates to the Balancer where the second hidden weight is to be placed.
24. Rotate the Wheel toward position -2- (to the left of the ideal position) and when all the Outer Plane indicators light and the Wheel locks, apply the correction weight shown in the Outer Display window position -2- on the Center Plane behind and as close to the Wheel Spoke as possible. 25.
