The angle of the vertical axis has been fixed before leaving the factory, please do not loosen the adjustment at will, please refer to the precautions.
N. Nylon paper guide roller frame, used to guide paper and tape without any adjustment.
O. O-rings, worn flat or need to be replaced after six months of use.
P. Sample stage, to hold flat samples
Q. Aluminum supply reels with 11/16” wide abrasive tape (Federal Spec. # UUT00126E)
R. Two weight reduction weights are installed on the left rear part of the rocker arm, so that the sample can bear a load of 55 or 175 grams.

T. 1/4" wide abrasive tape (RCA tape) for testing concave and elongated letters
U. to be determined
V. Hex wrench set
W pressure roller
X drive roller
Y 1/8 Thick Sheets (in an accessory box)
Z surface gauge to indicate that the sample is parallel to the surface of the instrument base
quick installation
Purpose:
When the sliding bolt (F) is moved back and forth slightly, there is slight resistance on the contact surface between the sliding bolt and the balance arm, and at the same time, the full weight of the vertical axis falls on the sample to be tested.
process:
1. Start the motor until the lift rocker arm (H) cam is in the lowest position to allow the cam follower bearing to be in the free position for cleaning.
2. Insert the sliding pin (F) so that the rocker arm rests on the flat surface of the sliding pin (F).
3. Loosen the two thumb clips and brass screws securing the vertical shaft (K), and move the vertical shaft (K) up and down so that the O-ring is in tight contact with the sample to be tested, while the rocker arm just touches the "F" slide pin planar section.
4. Retighten the brass screws
5. Turn the brass weight trim screw 'J' until there is slight resistance between the slide pin and the balance arm when you screw it in and out. This adjustment results in the rocker arm being parallel to the base of the instrument, allowing the set load to be applied to the sample.
6. Tighten the screw to fix the vertical axis in the adjusted position.
7. Remove pulley pin (F) under swing arm before run test.
测试不同厚度样品时，需要重新进行此项调整。
安装和操作
漆层表面性能即时磨耗测试
请确保磨耗介质上不含残留物质进而保证测试的准确性
重要注意事项：
导纸轮框架(N)中之4个尼龙轴承不能夹住纸张边缘。
同样地，供给卷轮'Q'亦不能防碍纸带或胶带之转动
在每天使用之前先取下O形环组合，清理O形环中心轮、轴承及其他所有接触的表面。
参考表面计页。
磨耗带宽度作调整时，只需要取出或放进位于前后卷轮'Q' 、'D '上的垫圈' T' 使磨耗带固定在机子上。#977机或更高机子则不须如此操作。
两个重量砝码'R' (55g和175g)用来测试热印式亮光薄膜，或者其它软性漆体测试。
当使用1/4"带宽时，如果你发现磨耗纸带磨面一边偏出卷轴，那么将带子扭到磨面朝下，不要磨带子的光面一边。
注意：用带子的哑面磨3倍于光面磨的效果。但也有不同的看法。
机器底座通过观察水平仪并调整垫脚螺丝来调平。
测试样品的安装
1. 滑动栓(F)移动至摇动臂下方，当凸轮接近最低位置时停止马达，摇动臂支撑于滑动栓上。
注意：凸轮与凸轮随动轴之间需要有空隙，摇动臂与滑轮栓之间不能有纸张。
2. 以单面或双面胶带将平行板样品固定与样品台上(P)上，亦可用所附之夹子将样品固定与砧台(P)上。以滚筒板式样品固定器(A)固定非平行表面之样品。以老虎钳式样品固定器(B)固定与圆形样品(须先将滚筒板式样品固定器上之平板取下)。以上方式固定样品时需利用表面计(Z)，以调整待测试之表面与一起成平行状态。
3. 降下垂直轴(K)(请先松开两个固定螺丝)，使得磨耗测试材料紧密的位于O 形环样品之间，再以手旋紧两个固定螺丝，与向上移动垂直轴(K)时，可以轻轻按住弹簧再移动，不要压按O形环或抬高摇动臂。
4. 将滑动栓(F)自摇动臂(H)底下移出。
5. 握住并抬高摇动臂(H)，以防止纸张接触样品，微动马达直至凸轮可支撑摇动臂(H)，而纸张不在样品上。
6. 计数器(G)归零 。
进行测试
Start the motor, and when the rocker arm is in the raised position, check whether the test area is worn to the substrate (whether the control color is different), this method is suitable for the standard rotary test. If it is a continuous abrasion test, stop the motor to view the results.
