Impex MARCY MWM-7150, Owner'S Manual

STEP 6   (See Diagram 6 & Cable Loop Diagram) 

A.)  Attach the 110” Lower Cable (#42) to the opening on the bottom of the Leg 

Developer (#7).  

B.)  Attach a Pulley (#26) to the opening. Secure it with one M10 x 2 ½” Allen Bolt 

(#53), two Ø 7/8” Bushings (#23), and one M10 Aircraft Nut (#56). 

C.)  Draw the Cable underneath the Pulley towards the back of the machine through 

the opening on the Front Post (#6) to the open bracket on rear of Front Post. 

D.)  Attach a Pulley to the bracket. Secure it with one M10 x 1 ¾” Allen Bolt (#54), 

two Ø ¾” Washers (#59), and one M10 Aircraft Nut (#56). 

E.)  Draw the Cable underneath the Pulley towards the back of the machine to the 

opening on the Main Base Frame (#1). Repeat Procedure B to install a Pulley. 

F.)  Draw the Cable around the Pulley then pull upward to the Double Floating Pulley 

Bracket (#11) previously installed in Step-5. Repeat Procedure D to install a 
Pulley.  

G.)  Draw the Cable around the Pulley then pull downward to the bracket on the rear 

of Main Frame. Secure the Cable to the bracket with one M10 x 1” Allen Bolt 
(#47), two 

∅

 ¾” Washers (#59) and one M10 Aircraft Nut (#56). 

H.)  Adjust the tension of the Cable system by adjusting the Pulley position on the 

Brackets. If the Cables are too loose, move the Pulley up one hole. If the Cables 
are too tight, move the Pulley down one hole. 

I.) 

For best performance of the machine, adjust the Cables so the Selector Stem 
(Top Plate) on the weight stack is ¼” above the first plate. To select the weight, 
push down on the Selector Stem to close the gap then insert the Weight Selector 
Pin. This will remove the slack in the cable system so the range of motion is 
smooth and tight. 

J.)  Attach the Ankle Strap (#44) to the Cable for various Leg exercises. Remove the 

Ankle Strap when using the Leg Developer. 

K.)  Lubricate the two Guide Rods with WD-40 or light oil.  This will minimize the 

friction on the Rods so the weight plates can slide up and down on the rods more 
freely.
