    5. Installation of the wheel balancer WARNING: These operations can be executed by persons who were earlier trained in servicing equipment described in this manual. To avoid possible wheel balancer damage or causing human injuries, it is necessary to preserve mentioned instructions. One must make sure nobody is within the working area of the machine.

  • Page 15: Place Of Installation

    2.1 Place of installation The wheel balancer should be installed in a locked, dry and heated (during autumn/winter season) room. Humidity should be between 30-95% with no vapor condensation. Temperature should be kept between 0-55 °C. The surface on which the wheel balancer will be standing should be hard and horizontal (best if concrete).

    5.3 Mounting car wheels' holder WARNING: The wheel balancer may be delivered with an already mounted holder. An assembled holder for car wheels with rims having a central mounting hole is shown in fig. 5.2. Before mounting the holder, clean the cone surface of the spindle and the surface of the holder (1, 2).

    5.5 Mounting motorcycle wheels' holder ATTENTION: Motorcycle wheels' holder is not standard equipment and - if needed - can be purchased separately WARNING: The wheel balancer may be delivered with an already mounted holder. Mounting motorcycle wheels' holder is very similar to mounting car wheels' holder, which was described in chapter 5.3.

  • Page 19: Fixing Wheels On Wheel Balancer's Holders

    5.7 Fixing wheels on wheel balancer's holders 5.7.1 Car wheel Figure 5.7 shows four stages of mounting a car wheel on the wheel balancer's holder. Firstly, one has to slide the wheel on the radix of the holder (fig. 5.7(a)) and hang its hole's edge on the centering cone (fig.
  • Page 20 Construction and equipment of the holder make it possible to mount wheels with different rim shapes and different central hole diameters which is shown in figure 5.9. If using оде of the centering cones, the wheel should be mounted from the outer side like in fig. 5.9(a) and 5.9(д), without using nut clamp 5 nor cone spring 4 (fig.

    5.7.2 Mounting the spike holder ATTENTION: Spike holder is not standard equipment and - if needed - can be purchased separately. Spike holder, presented and described in figure 5.11 is used for wheels without a central hole. Wheels having 3,4, 5 and 6 holes can be mounted on the holder. Due to the fact that mounting a spike holder is dependent on the balanced wheel, the whole procedure has been described in chapter 5.7.3 .

    Working with the machine 6.1 Connecting the machine to a power outlet ATTENTION: Connect the power cord to a 230V/50Hz power outlet. ATTENTION: because rapid heating of a frozen metal and plastic body results in lots of condensation on its surface, one should not plug a cold machine into a power outlet until 2 to 3 hours have passed required for all the electronic elements to dry and reach the ambient temperature.

    6.6.1 User memory Wheel balancers are equipped with internal memory, in which the operator can store four sets of wheel parameters. These parameters are: Diameter, Width, Distance and ALU (weight placement). Memory tiding; Pressing results in entering memory reading mode. The following screen appears c Using the ъ...

  • Page 29: Balancing A Wheel

    6.7 Balancing a wheel Balancing any wheel comes to evaluating the imbalance values for both internal and external correction planes and locating its position on the wheel. To correctly calculate these values one should input following data: WIDTH- DIAMETER-'^^Д, D I S T A N C E - c h o o s e weight placement and change threshold if necessary. A measurement cycle after firmly mounting the wheel in the holder is initiated by closing the hood if AUTOSTART is activated, pressing B^^b- after closing the hood or pressing at the same time without closing the hood - NOT RECOMMENDED.

  • Page 30: Optimisation

    6.9 Optimisation ATTENTION: Optimization is to be performed as a preliminary operation to wheel balancing using correction weights. Optimization is a control test of a wheel providing rim and tyre alignment checking to ensure that imbalances coming from both cancel each other out. It helps diminishing the imbalance of the wheel and using smaller weights.

  • Page 31: Hidden Weight" Program - 3P

    6.10 "Hidden weight" program - 3P The "hidden weight" program breaks downa single imbalance point. It is only available for weight placement modes (3), and (5), (table 6.2). This function is used to break down the value and position of imbalance correction into two separate values and points so that the adhesive weights can be hidden behind the rim’s spoke thanks to which they are not visible from outside (for a car wheel, modes 4 and 5) or split the imbalance so that it is possible to omit the spoke, which is exactly in the weight placement point (for motorcycle...

  • Page 32: Calibration

    6.11 Calibration Attention! Each sold machine is already calibrated! Calibration is advised only in a situation where there exists a probability of machine recalibration (if e.g. displayed imbalance values do not reflect actual values). Calibration process is about providing a pattern and saving in the machine’s memory its reaction to it.
