Be sure to exercise the “Mandatory Shut-down Procedure”, (section 1, page 2) before attempting any type of cleaning or maintenance. Storage: Storage at the end of the snow removal season or between each use, requires an inspection of the snowblower for repairs and general upkeep to insure it will be ready for future use. Below is a list of suggestions. • With engine stopped, ignition key removed, and PTO disengaged, clean the snowblower, especially in areas of drive chain, fan, spout, and auger where it could become frozen or rusted together and cause damage when unit is N14809 11 • Repair or replace worn parts. • Coat moving parts and high wear areas with oil, especially the chains and lubricate all grease fitting. • Repaint all parts and areas where the paint has become removed to prevent rusting. • Store the snowblower in a dry place. 1/01 Owner’s Manual (Snowblower) Torque Charts Minimum Hardware Tightening Torques In Foot Pounds (Newton-Metres) for Normal Assembly Applications Inches Hardware and Lock Nuts SAE Gr. 2 Nominal Size SAE Grade 5 SAE Grade 8 Lock Nuts Unplated Plated Unplated Plated Unplated Plated Grade or W/ZnCr or W/ZnCr or W/ZnCr W/Gr.5 Plated Plated Plated Bolt Silver Gold Silver Gold Silver Gold Grade W/Gr.8 Bolt 1/4 55* (6.2) 112* (13) 121* (14) 157* (18) 61* (6..9) 86* (9.8) 5/16 115* (13) 149* (17) 178* (20) 229* (26) 250* (28) 324* (37) 125* (14) 176* (20) 72* (8.1) 86* (9.7) 3/8 17 (23) 22 (30) 26 (35) 34 (46) 37 (50) 48 (65) 19 (26) 26 (35) 7/16 27 (37) 35 (47) 42 (57) 54 (73) 59 (80) 77 (104) 30 (41) 42 (57) 1/2 42 (57) 54 (73) 64 (87) 83 (113) 91 (123) 117 (159) 45 (61) 64 (88) 9/16 60 (81) 77 (104) 92 (125) 120 (163) 130 (176) 169 (229) 65 (88) 92 (125) 5/8 83 (112) 107 (145) 128 (174) 165 (224) 180 (244) 233 (316) 90 (122) 127 (172) 3/4 146 (198) 189 (256) 226 (306) 293 (397) 319 (432) 413 (560) 160 (217) 226 (306) 7/8 142 (193) 183 (248) 365 (495) 473 (641) 515 (698) 667 (904) 1 N14809 258 (350) 364 (494) 213 (289) 275 (373) 547 (742) 708 (960) 773 (1048) 1000 (1356) 386 (523) 545 (739) 12 1/01 Owner’s Manual (Snowblower) Torque Charts Minimum Hardware Tightening Torque Inch Pounds for Normal Assembly Applications Metric Hardware and Lock Nuts Class 5.8 Nominal Size Class 8.8 Class 10.9 Lock Nuts Unplated Plated Unplated Plated or W/ZnCr or W/ZnCr Plated Plated Silver Gold Silver Gold Unplated or Plated Silver Plated W/ZnCr Class 8 W/CL.8.8 Bolt M4 15* (107) 19* (2.2) 23* (2.6) 30* (3.4) 33* (3.7) 42* (4.8) 16* (1.8) M6 51* (5.8) 67* (7.6) 79* (8.9) 102* (12) 115* (13) 150* (17) 56* (6.3) M8 124* (14) 159* (18) 195* (22) 248* (28) 274* (31) 354* (40) 133* (15) Gold M10 21 (28) 27 (36) 32 (43) 41 (56) 45 (61) 58 (79) 22 (30) M12 36 (49) 46 (63) 55 (750 72 (97) 79 (107) 102 (138) 39 (53) M16 89 (121) 117 (158) 137 (186) 177 (240) 196 (266) 254 (344) 97 (131) M20 175 (237) 226 (307) 277 (375) 358 (485) 383 (519) 495 (671) 195 (265) M24 303 (411) 392 (531) 478 9648) 619 (839) 662 (897) 855 (1160) 338 (458) N14809 13 1/01 Section 4 Service Parts Owner’s Manual (Snowblower) Service Parts Ordering Service Parts: To assist our customer service department in providing you with the correct replacement parts promptly and accurately, follow the ordering instructions as listed below. 1.
